+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+                    675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+Tue Dec 10 04:14:49 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
+
+	* Makefile.in: infodir belongs in datadir.
+
+Fri Dec  6 23:26:45 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
+
+	* Makefile.in: remove spaces following hyphens because bsd make
+	  can't cope.  added standards.text support.  install using
+	  INSTALL_DATA.
+
+	* configure.in: remove commontargets as it is no longer a
+	  recognized hook.
+
+Thu Dec  5 22:46:46 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
+
+	* Makefile.in: idestdir and ddestdir go away.  Added copyrights
+	  and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
+	  and mandir now keyed off datadir by default.
+
+Fri Nov 22 19:15:29 1991  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.in:  find-needed.awk does not fit in 14 chars.
+
+	* Makefile.in:  Suppress error checking when compiling the test
+	program, because Ultrix make/sh aborts there due to a bug.
+
+Fri Nov 22 12:23:17 1991  Per Bothner  (bothner at cygnus.com)
+
+	* Makefile.in:  Re-did how EXTRA_OFILES is used to be more useful.
+	* README:  Explained how the auto-configuration works,
+	and how to add new files and/or configurations.
+
+Fri Nov 22 09:45:23 1991  John Gilmore  (gnu at cygnus.com)
+
+	* strtoul.c:  Avoid defining ULONG_MAX if already defined;
+	cast a const char * to char * for pedants.
+
+	* getopt.c:  Only define "const" after local include files get to,
+	and only if they haven't defined it.
+
+Thu Nov 21 16:58:53 1991  John Gilmore  (gnu at cygnus.com)
+
+	* getcwd.c (remove getwd.c): GNU code should call getcwd().  We
+	emulate it with getwd() if available.  This avoids callers having
+	to find a MAXPATHLEN or PATH_MAX value from somewhere.
+	* Makefile.in, functions.def:  getwd->getcwd.
+	* configure.in:  Use generic case for every system.
+	* config/mh-{delta88,mach,rs6000,svr4}:  Remove.
+	* config/mh-sysv:  Use default handling, just add -DUSG.
+
+Thu Nov 14 10:58:05 1991  Per Bothner  (bothner at cygnus.com)
+
+	* Makefile.in, config/mh-default: Re-do make magic
+	so that for the default ("automatic") mode we only
+	compile the files we actually need.  Do this using
+	a recursive make:  The top-level generates the list
+	of needed files (loosely, the ones missing in libc),
+	and then passes that list to the recursive make.
+	* config/mh-mach:  Remove obsolete STRERROR-{C,O} macros.
+
+Tue Nov 12 19:10:57 1991  John Gilmore  (gnu at cygnus.com)
+
+	RS/6000 host support (grumble).
+
+	* configure.in:  Build alloca-conf.h file from alloca-norm.h
+	(everything else) or alloca-botch.h (rs/6000).
+	* Makefile.in:  Include . on the include path.
+	* getopt.c:  Use alloca-conf.h.
+	* alloca-norm.h:  How to declare alloca on reasonable machines.
+	* alloca-botch.h: How to declare alloca on braindead machines.
+
+Tue Nov 12 09:21:48 1991  Fred Fish  (fnf at cygnus.com)
+
+	* concat.c :  New file, like concat() in gdb but can take a
+	variable number of arguments rather than fixed at 3 args.  For
+	now, client applications must supply an xmalloc(), which is a
+	front end function to malloc() that deals with out-of-memory
+	conditions.
+
+	* Makefile.in:  Add concat.c and concat.o to appropriate macros.
+
+Sat Nov  9 13:29:59 1991  Fred Fish  (fnf at cygnus.com)
+
+	* config/mh-svr4:  Add sigsetmask to list of required functions.
+
+Sun Nov  3 11:57:56 1991  Per Bothner  (bothner at cygnus.com)
+
+	* vsprintf.c:  New file.
+	* functions.def, Makefile.in:  Add vsprintf.
+
+Sun Oct 27 16:31:22 1991  John Gilmore  (gnu at cygnus.com)
+
+	* configure.in, config/mh-rs6000:  Add rs/6000 host support.
+	* Makefile.in:  Compile with debug info.
+
+Fri Oct 25 17:01:12 1991  Per Bothner  (bothner at cygnus.com)
+
+	* Makefile.in, configure.in, and new files: dummy.c, functions.def,
+	config/mf-default:  Added a default configuration mode,
+	which includes into libiberty.a functions that are "missing" in libc.
+	* strdup.c, vprintf.c, vfprintf.c: New files.
+
+Thu Oct 24 02:29:26 1991  Fred Fish  (fnf at cygnus.com)
+
+	* config/hmake-svr4: New file.
+
+	* config/hmake-sysv: Add HOST_CFILES and HOST_OFILES.
+
+	* basename.c, bcmp.c, bcopy.c, bzero.c, getpagesize.c getwd.c,
+	index.c, insque.c, rindex.c, spaces.c, strstr.c, vfork.c: New
+	files containing either portable C versions or emulations using
+	native library calls.
+
+	* strerror.c:  Add copyright, internal documentation, etc.
+
+	* strtol.c:  Replace hardwired hex constants with some more
+	portable macros.  Remove illegal (according to gcc) cast.
+
+	* strtoul.c: Replace hardwired hex constant with more portable
+	macro.
+
+	* Makefile.in: Move TARGETLIB and CFLAGS where makefile fragments
+	can override them.  Add new source and object file names to CFILES
+	and OFILES respectively.
+
+	* configure.in: Add support for SVR4 makefile fragments.
+
+Tue Oct 22 19:00:23 1991  Steve Chamberlain  (steve at cygnus.com)
+
+	* Makefile.in: Move RANLIB, AR and AR_FLAGS to where they can be
+	over-ridden by config/hmake-*
+	* configure.in: added m88kcvs to sysv list
+
+Fri Oct  4 01:29:08 1991  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.in:  Most hosts need strerror, but one or two don't,
+	and they override these definitions in the host-dependent makefile
+	fragment.
+	* config/hmake-mach:  The odd man out on strerror -- it's supplied.
+	* strerror.c:  New file.
+
+	* strtol.c, strtoul.c:  Add strtol to libiberty, since Mach lacks
+	it and bfd uses it.
+	* configure.in, Makefile.in, config/hmake-mach:  Only configure
+	strtol & strotoul in on Mach.
+
+Tue Sep  3 06:36:23 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* obstack.c:  Merge with latest FSF version.

+This directory contains the -liberty library of free software.
+It is a collection of subroutines used by various GNU programs.
+Current members include:
+
+	getopt -- get options from command line
+	obstack -- stacks of arbitrarily-sized objects
+	strerror -- error message strings corresponding to errno
+	strtol -- string-to-long conversion
+	strtoul -- string-to-unsigned-long conversion
+
+We expect many of the GNU subroutines that are floating around to
+eventually arrive here.
+
+To build the library, do:
+
+	./configure HOSTTYPE
+	make
+
+Please report bugs and fixes to "bug-gnu-utils@prep.ai.mit.edu".  Thank you.
+
+ADDING A NEW FILE
+=================
+
+There are two sets of files:  Those that are "required" will be
+included in the library for all configurations, while those
+that are "optional" will be included in the library only if "needed."
+
+To add a new required file, edit Makefile to add the source file
+name to CFILES and the object file to REQUIRED_OFILES.
+
+Adding a new optional file is more fragile.  As a general rule,
+an optional file will be included in the library if it provides
+functionality missing in the "standard" C library.
+For most hosts, the Makefile automatically figures out which
+functionality is missing by compiling and linking a dummy test
+program, and examining the error messages.
+
+So to get this to work, you should do the following:
+
+1) Select one function defined in the file you're adding.
+For example, the getcwd function.
+2) Add that function to the list in the file functions.def.
+3) The name of the new file must be the same as the function
+you've chosen with the .c suffix added.  E.g. getcwd() must be
+defined in getcwd.c.  (The file can define other functions as well.)
+4) In Makefile.in, add the name of the source file (e.g. getcwd.c)
+to CFILES.
+
+The file you've added (e.g. getcwd.c) should compile and work
+on all hosts where it is needed (e.g. not found when linking
+the dummy.c program).  It does not have to work or even
+compile on hosts where it is not needed.
+
+HOW THE AUTOMATIC CONFIGURATION WORKS
+=====================================
+
+The libiberty.a target (in RULE1) depends on $(DO_ALSO).
+For normal configurations, DO_ALSO=needed-list.
+
+So needed-list is first made.  The needed-list rule compiles
+dummy.c.  Because dummy.c includes functions.def, the
+resulting object file will contain a call to each of the
+optional functions (for simplicity assume each optional file
+defines a single function).  This object file will be linked
+against the standard libraries (as defined by using $(CC)
+and various flags).  Any function missing will causes the
+linker to emit an error message.  We assume the name
+of the missing function(s) are in the error message(s).
+The awk script find-needed.awk has been generated from
+functions.def.  It is used to search the linker output
+messages for words that match the functions listed in
+functions.def.  The list of functions found is written
+on a single line to the file needed-list.
+
+After needed-list has been generated, the libiberty.a
+target (in RULE1) just calls 'make' recursively.
+It passes the contents of needed-list using the
+definition (expanded) HOST_OFILES="`cat needed-list`".
+It also tells the inferior 'make' to use RULE2.
+
+The inferior 'make' is very conventional:  The main
+rule is $(RULE2) (which is libiberty.a).  It depends
+on a list of object files: $(REQUIRED_OFILES) $(HOST_OFILES)
+(and $(EXTRA_OFILES), which is usually empty).  The superior
+'make' passes in $(HOST_OFILES); the others are fixed
+in the Makefile.
+
+ADDING A NEW CONFIGURATION
+==========================
+
+On most hosts you should be able to use the scheme for automatically
+figuring out which files are needed.  In that case, you probably
+don't need a special Makefile stub for that configuration.
+
+If the fully automatic scheme doesn't work, you may be able to get
+by with defining EXTRA_OFILES in your Makefile stub.  This is
+a list of object file names that should be treated as required
+for this configuration - they will be included in libiberty.a,
+regardless of whatever might be in the C library.  Moreover,
+when the dummy.c program is linked, it will be linked with
+$(EXTRA_OFILES).  Therefore, if a function in functions.def
+is defined by one of the EXTRA_OFILES, it will not be listed as
+"needed".  Thus if your hal9000 host needs a special implementation
+of getcwd, you can just create hal9000-getcwd.c, and define:
+	EXTRA_OFILES=hal9000-getcwd.o
+Or if you want to use the libiberty version of strstr(),
+even though there is a version in the C library (it might be
+buggy or slow), just define:
+	EXTRA_OFILES=strstr.o
+
+You can create a "manual" host configuration FOO with a file
+config/mh-FOO.  In it, the HOST_OFILES macro should explicitly
+list that subset of the optional files that should be in the
+library.  You should also set:
+	DO_ALSO =
+This overrides all of the magic needed to automatically
+determine which files are "needed."  However, keeping that list
+up to date is another matter...
+
+HOW THE MANUAL CONFIGURATION WORKS
+==================================
+
+This also uses a recursive make, but the superior make
+does not do anything interesting - it just calls the
+inferior make with HOST_OFILES defined as $(HOST_OFILES),
+which is the list you created in your configuration.
+
+You probably don't want to depend on manual configuration,
+because keeping the HOST_OFILES list up-to-date will be a pain.

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

+	returned result of buildargv, as it's argument.
+
+	The memory for the argv array is dynamically expanded as necessary.
+
+RETURNS
+
+	Returns a pointer to the argument vector if successful. Returns NULL
+	if the input string pointer is NULL or if there is insufficient
+	memory to complete building the argument vector.
+
+NOTES
+
+	In order to provide a working buffer for extracting arguments into,
+	with appropriate stripping of quotes and translation of backslash
+	sequences, we allocate a working buffer at least as long as the input
+	string.  This ensures that we always have enough space in which to
+	work, since the extracted arg is never larger than the input string.
+
+	If the input is a null string (as opposed to a NULL pointer), then
+	buildarg returns an argv that has one arg, a null string.
+
+	Argv is always kept terminated with a NULL arg pointer, so it can
+	be passed to freeargv at any time, or returned, as appropriate.

+
+DESCRIPTION
+
+	Concatenate a variable number of strings and return the result
+	in freshly malloc'd memory.
+
+	Returns NULL if insufficient memory is available.  The argument
+	list is terminated by the first NULL pointer encountered.  Pointers
+	to empty strings are ignored.
+
+NOTES
+
+	This function uses xmalloc() which is expected to be a front end
+	function to malloc() that deals with low memory situations.  In
+	typical use, if malloc() returns NULL then xmalloc() diverts to an
+	error handler routine which never returns, and thus xmalloc will
+	never return a NULL pointer.  If the client application wishes to
+	deal with low memory situations itself, it should supply an xmalloc
+	that just directly invokes malloc and blindly returns whatever
+	malloc returns.

+
+SYNOPSIS
+

+	demangle_signature (struct work_stuff *work, const char **mangled,
+			    string *declp);
+
+DESCRIPTION
+
+	Consume and demangle the signature portion of the mangled name.
+
+	DECLP is the string where demangled output is being built.  At
+	entry it contains the demangled root name from the mangled name
+	prefix.  I.E. either a demangled operator name or the root function
+	name.  In some special cases, it may contain nothing.
+
+	*MANGLED points to the current unconsumed location in the mangled
+	name.  As tokens are consumed and demangling is performed, the
+	pointer is updated to continuously point at the next token to
+	be consumed.
+
+	Demangling GNU style mangled names is nasty because there is no
+	explicit token that marks the start of the outermost function
+	argument list.  */

+
+   g++ produces the names:

+     foo__FiR3fooiT1iT1
+
+   while lcc (and presumably other ARM style compilers as well) produces:
+
+     foo__FiR3fooT1T2T1T2
+     __ct__3fooFiR3fooT1T2T1T2
+
+   Note that g++ bases it's type numbers starting at zero and counts all
+   previously seen types, while lucid/ARM bases it's type numbers starting
+   at one and only considers types after it has seen the 'F' character
+   indicating the start of the function args.  For lucid/ARM style, we
+   account for this difference by discarding any previously seen types when
+   we see the 'F' character, and subtracting one from the type number
+   reference.

+NAME

+
+SYNOPSIS
+
+	int fdmatch (int fd1, int fd2)
+
+DESCRIPTION
+
+	Check to see if two open file descriptors refer to the same file.
+	This is useful, for example, when we have an open file descriptor
+	for an unnamed file, and the name of a file that we believe to 
+	correspond to that fd.  This can happen when we are exec'd with
+	an already open file (stdout for example) or from the SVR4 /proc
+	calls that return open file descriptors for mapped address spaces.
+	All we have to do is open the file by name and check the two file
+	descriptors for a match, which is done by comparing major&minor
+	device numbers and inode numbers.
+
+BUGS
+
+	(FIXME: does this work for networks?)
+	It works for NFS, which assigns a device number to each mount.

+

+   This mode of operation is selected by either setting the environment

+   to expect options and other ARGV-elements in any order and that care about
+   the ordering of the two.  We describe each non-option ARGV-element
+   as if it were the argument of an option with character code 1.
+   Using `-' as the first character of the list of option characters
+   selects this mode of operation.

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns `EOF'.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce

+
+	Returns the number of bytes in a page of memory.  This is the

+
+	Is intended as a reasonable replacement for systems where this
+	is not provided as a system call.  The value of 4096 may or may
+	not be correct for the systems where it is returned as the default

+   PROGRAM and ARGV are the arguments to execv/execvp.
+
+   THIS_PNAME is name of the calling program (i.e. argv[0]).
+
+   TEMP_BASE is the path name, sans suffix, of a temporary file to use
+   if needed.  This is currently only needed for MSDOS ports that don't use
+   GO32 (do any still exist?).  Ports that don't need it can pass NULL.
+
+   (FLAGS & PEXECUTE_SEARCH) is non-zero if $PATH should be searched
+   (??? It's not clear that GCC passes this flag correctly).
+   (FLAGS & PEXECUTE_FIRST) is nonzero for the first process in chain.
+   (FLAGS & PEXECUTE_FIRST) is nonzero for the last process in chain.
+   FIRST_LAST could be simplified to only mark the last of a chain of processes
+   but that requires the caller to always mark the last one (and not give up
+   early if some error occurs).  It's more robust to require the caller to
+   mark both ends of the chain.
+
+   The result is the pid on systems like Unix where we fork/exec and on systems
+   like WIN32 and OS2 where we use spawn.  It is up to the caller to wait for
+   the child.
+
+   The result is the WEXITSTATUS on systems like MSDOS where we spawn and wait
+   for the child here.
+
+   Upon failure, ERRMSG_FMT and ERRMSG_ARG are set to the text of the error
+   message with an optional argument (if not needed, ERRMSG_ARG is set to
+   NULL), and -1 is returned.  `errno' is available to the caller to use.
+
+   pwait: cover function for wait.
+
+   PID is the process id of the task to wait for.
+   STATUS is the `status' argument to wait.
+   FLAGS is currently unused (allows future enhancement without breaking
+   upward compatibility).  Pass 0 for now.
+
+   The result is the pid of the child reaped,
+   or -1 for failure (errno says why).
+
+   On systems that don't support waiting for a particular child, PID is
+   ignored.  On systems like MSDOS that don't really multitask pwait
+   is just a mechanism to provide a consistent interface for the caller.
+
+   pfinish: finish generation of script

+/* An improved random number generation package.  In addition to the standard
+   rand()/srand() like interface, this package also has a special state info
+   interface.  The initstate() routine is called with a seed, an array of
+   bytes, and a count of how many bytes are being passed in; this array is
+   then initialized to contain information for random number generation with
+   that much state information.  Good sizes for the amount of state
+   information are 32, 64, 128, and 256 bytes.  The state can be switched by
+   calling the setstate() function with the same array as was initiallized
+   with initstate().  By default, the package runs with 128 bytes of state
+   information and generates far better random numbers than a linear
+   congruential generator.  If the amount of state information is less than
+   32 bytes, a simple linear congruential R.N.G. is used.  Internally, the
+   state information is treated as an array of longs; the zeroeth element of
+   the array is the type of R.N.G. being used (small integer); the remainder
+   of the array is the state information for the R.N.G.  Thus, 32 bytes of
+   state information will give 7 longs worth of state information, which will
+   allow a degree seven polynomial.  (Note: The zeroeth word of state
+   information also has some other information stored in it; see setstate
+   for details).  The random number generation technique is a linear feedback
+   shift register approach, employing trinomials (since there are fewer terms
+   to sum up that way).  In this approach, the least significant bit of all
+   the numbers in the state table will act as a linear feedback shift register,
+   and will have period 2^deg - 1 (where deg is the degree of the polynomial
+   being used, assuming that the polynomial is irreducible and primitive).
+   The higher order bits will have longer periods, since their values are
+   also influenced by pseudo-random carries out of the lower bits.  The
+   total period of the generator is approximately deg*(2**deg - 1); thus
+   doubling the amount of state information has a vast influence on the
+   period of the generator.  Note: The deg*(2**deg - 1) is an approximation
+   only good for large deg, when the period of the shift register is the
+   dominant factor.  With deg equal to seven, the period is actually much
+   longer than the 7*(2**7 - 1) predicted by this formula.  */
