+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, 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., 59 Temple Place - Suite 330, Boston,
+ MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.

+ to demangle the funct args, then handle the LUCID_DEMANGLING,
+ ARM_DEMANGLING, and EDG_DEMANGLING styles. Add case for local
+ class name after "Lnnn_ in HP style case. HP style too needs to
+ forget types. _nnn is OK for HP style, so don't report failure.

+
+Mon Jun 15 01:03:26 1992 John Gilmore (gnu at cygnus.com)
+
+ * sigsetmask.c: Rewrite. Old one was very confused about its
+ arguments and result. New one can't do much, but at least knows

+
+Mon Apr 20 12:57:46 1992 Per Bothner (bothner@rtl.cygnus.com)
+
+ * config/mh-aix: New. EXTRA_OFILES lists copysign.o,
+ so libg++ users don't have to be inconvenienced by a

+Thu Dec 19 18:35:03 1991 John Gilmore (gnu at cygnus.com)
+

+
+ * memcmp.c, memcpy.c, memmove.c, memset.c, strchr.c, strrchr.c:

+
+ * Makefile.in: Re-did how EXTRA_OFILES is used to be more useful.

+
+Thu Nov 21 16:58:53 1991 John Gilmore (gnu at cygnus.com)

+ * getcwd.c (remove getwd.c): GNU code should call getcwd(). We

+ * configure.in: Use generic case for every system.
+ * config/mh-{delta88,mach,rs6000,svr4}: Remove.

+
+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)

+
+ * Makefile.in: Add concat.c and concat.o to appropriate macros.
+
+Sat Nov 9 13:29:59 1991 Fred Fish (fnf at cygnus.com)

+
+ * strtoul.c: Replace hardwired hex constant with more portable

+
+ * configure.in: Add support for SVR4 makefile fragments.
+
+Tue Oct 22 19:00:23 1991 Steve Chamberlain (steve at cygnus.com)

+ * configure.in: added m88kcvs to sysv list
+
+Fri Oct 4 01:29:08 1991 John Gilmore (gnu at cygnus.com)

+ 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.
+

+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.
+
+The library must be configured from the top source directory. Don't
+try to run configure in this directory. Follow the configuration
+instructions in ../README.
+
+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.
+
+To add a new optional file, it must provide a single function, and the
+name of the function must be the same as the name of the file.
+
+ * Add the source file name to CFILES.
+
+ * Add the function to name to the funcs shell variable in
+ configure.in.
+
+ * Add the function to the AC_CHECK_FUNCS lists just after the
+ setting of the funcs shell variable. These AC_CHECK_FUNCS calls
+ are never executed; they are there to make autoheader work
+ better.
+
+ * Consider the special cases of building libiberty; as of this
+ writing, the special cases are newlib and VxWorks. If a
+ particular special case provides the function, you do not need
+ to do anything. If it does not provide the function, add the
+ object file to LIBOBJS, and add the function name to the case
+ controlling whether to define HAVE_func.
+
+The optional file you've added (e.g. getcwd.c) should compile and work
+on all hosts where it is needed. It does not have to work or even
+compile on hosts where it is not needed.
+
+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.

+/* 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. */

+ buildargv -- build an argument vector from a string

+SYNOPSIS

+ char *sp;
+
+DESCRIPTION
+
+ Given a pointer to a string, parse the string extracting fields
+ separated by whitespace and optionally enclosed within either single
+ or double quotes (which are stripped off), and build a vector of
+ pointers to copies of the string for each field. The input string
+ remains unchanged.
+
+ All of the memory for the pointer array and copies of the string
+ is obtained from malloc. All of the memory can be returned to the
+ system with the single function call freeargv, which takes the
+ 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.

+
+SYNOPSIS
+
+ #include <varargs.h>
+
+ char *concat (s1, s2, s3, ..., NULL)
+
+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
+
+ static int
+ 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. */

+SYNOPSIS

+ get_count (const char **type, int *count)
+
+DESCRIPTION
+
+ Assume that *type points at a count in a mangled name; set
+ *count to its value, and set *type to the next character after
+ the count. There are some weird rules in effect here.
+
+ If *type does not point at a string of digits, return zero.
+
+ If *type points at a string of digits followed by an
+ underscore, set *count to their value as an integer, advance
+ *type to point *after the underscore, and return 1.
+
+ If *type points at a string of digits not followed by an
+ underscore, consume only the first digit. Set *count to its
+ value as an integer, leave *type pointing after that digit,
+ and return 1.
+
+ The excuse for this odd behavior: in the ARM and HP demangling
+ styles, a type can be followed by a repeat count of the form
+ `Nxy', where:
+
+ `x' is a single digit specifying how many additional copies
+ of the type to append to the argument list, and
+
+ `y' is one or more digits, specifying the zero-based index of
+ the first repeated argument in the list. Yes, as you're
+ unmangling the name you can figure this out yourself, but
+ it's there anyway.
+
+ So, for example, in `bar__3fooFPiN51', the first argument is a
+ pointer to an integer (`Pi'), and then the next five arguments
+ are the same (`N5'), and the first repeat is the function's
+ second argument (`1').

+ indicating the start of the function args. For lucid/ARM style, we

+NAME
+
+ fdmatch -- see if two file descriptors refer to same file
+
+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.

+/* 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 -1.
+ 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
+ long-named options. */

+ Returns the number of bytes in a page of memory. This is the
+ granularity of many of the system memory management routines.
+ No guarantee is made as to whether or not it is the same as the
+ basic memory management hardware page size.
+
+BUGS
+
+ 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
+ value.

+
+ 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
+
+ pfinish is necessary for systems like MPW where a script is generated that
+ runs the requested programs.

+/* 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. */
