+=head1 NAME
+
+README.hints
+
+=head1 DESCRIPTION
+
+These files are used by Configure to set things which Configure either
+can't or doesn't guess properly.  Most of these hint files have been
+tested with at least some version of perl5, but some are still left
+over from perl4.
+
+Please send any problems or suggested changes to perlbug@perl.org.
+
+=head1 Hint file naming convention.
+
+Each hint file name should have only
+one '.'.  (This is for portability to non-unix file systems.)  Names
+should also fit in <= 14 characters, for portability to older SVR3
+systems.  File names are of the form $osname_$osvers.sh, with all '.'
+changed to '_', and all characters (such as '/') that don't belong in
+Unix filenames omitted.
+
+For example, consider Sun OS 4.1.3.  Configure determines $osname=sunos
+(all names are converted to lower case) and $osvers=4.1.3.  Configure
+will search for an appropriate hint file in the following order:
+
+	sunos_4_1_3.sh
+	sunos_4_1.sh
+	sunos_4.sh
+	sunos.sh
+
+If you need to create a hint file, please try to use as general a name
+as possible and include minor version differences inside case or test
+statements.  For example, for IRIX 6.X, we have the following hints
+files:
+
+	irix_6_0.sh
+	irix_6_1.sh
+	irix_6.sh
+
+That is, 6.0 and 6.1 have their own special hints, but 6.2, 6.3, and
+up are all handled by the same irix_6.sh.  That way, we don't have to
+make a new hint file every time the IRIX O/S is upgraded.
+
+If you need to test for specific minor version differences in your
+hints file, be sure to include a default choice.  (See aix.sh for one
+example.) That way, if you write a hint file for foonix 3.2, it might
+still work without any changes when foonix 3.3 is released.
+
+Please also comment carefully on why the different hints are needed.
+That way, a future version of Configure may be able to automatically
+detect what is needed.
+
+A glossary of config.sh variables is in the file Porting/Glossary.
+
+=head1 Setting variables
+
+=head2 Optimizer
+
+If you want to set a variable, try to allow for Configure command-line
+overrides.  For example, suppose you think the default optimizer
+setting to be -O2 for a particular platform.  You should allow for
+command line overrides with something like
+
+	case "$optimize" in
+	'') optimize='-O2' ;;
+	esac
+
+or, if your system has a decent test(1) command,
+
+	test -z "$optimize" && optimize='-O2'
+
+This allows the user to select a different optimization level, e.g.
+-O6 or -g.
+
+=head2 Compiler and Linker flags
+
+If you want to set $ccflags or $ldflags, you should append to the existing
+value to allow Configure command-line settings, e.g. use
+
+	ccflags="$ccflags -DANOTHER_OPTION_I_NEED"
+
+so that the user can do something like
+
+	sh Configure -Dccflags='FIX_NEGATIVE_ZERO'
+
+and have the FIX_NEGATIVE_ZERO value preserved by the hints file.
+
+=head2 Libraries
+
+Configure will attempt to use the libraries listed in the variable
+$libswanted.  If necessary, you should remove broken libraries from
+that list, or add additional libraries to that list.  You should
+*not* simply set $libs -- that ignores the possibilities of local
+variations.  For example, a setting of libs='-lgdbm -lm -lc' would
+fail if another user were to try to compile Perl on a system without
+GDBM but with Berkeley DB.  See hints/dec_osf.sh and hints/solaris_2.sh
+for examples.
+
+=head2 Other
+
+In general, try to avoid hard-wiring something that Configure will
+figure out anyway.  Also try to allow for Configure command-line
+overrides.
+
+=head1 Working around compiler bugs
+
+Occasionally, the root cause of a bug in perl turns out to be due to a bug
+in the compiler.  Often, changing the compilation options (particularly the
+optimization level) can work around the bug.  However, if you try to do
+this on the command line, you will be changing the compilation options for
+every component of perl, which can really hurt perl's performance.
+Instead, consider placing a test case into the hints directory to detect
+whether the compiler bug is present, and add logic to the hints file to
+take a specific and appropriate action
+
+=head2 Test-case conventions
+
+Test cases should be named "tNNN.c", where NNN is the next unused sequence
+number.  The test case must be executable and should display a message
+containing the word "fails" when the compiler bug is present.  It should
+display the word "works" with the compiler bug is not present.  The test
+cases should be liberally commented and may be used by any hints file that
+needs them.  See the first hints file (t001.c) for an example.
+
+=head2 Hint file processing
+
+The hint file must define a call-back unit (see below) that will compile,
+link, and run the test case, and then check for the presence of the string
+"fails" in the output.  If it finds this string, it sets a special variable
+to specify the compilation option(s) for the specific perl source file that
+is affected by the bug.
+
+The special variable is named "XXX_cflags" where "XXX" is the name of
+the source file (without the ".c" suffix).  The value of this variable
+is the string "optimize=YYY", where "YYY" is the compilation option
+necessary to work around the bug.  The default value of this variable
+is "-O" (letter O), which specifies that the C compiler should compile
+the source program at the default optimization level.  If you can
+avoid the compiler bug by disabling optimization, just reset the
+"optimize" variable to the null string.  Sometimes a bug is present at
+a higher optimization level (say, O3) and not present at a lower
+optimization level (say, O1).  In this case, you should specify the
+highest optimization level at which the bug is not present, so that
+you will retain as many of the benefits of code optimization as
+possible.
+
+For example, if the pp_pack.c source file must be compiled at
+optimization level 0 to work around a problem on a particular
+platform, one of the statements
+
+	pp_pack_cflags="optimize=-O0"	or
+	pp_pack_cflags="optimize="
+
+will do the trick, since level 0 is equivalent to no optimization.
+(In case your printer or display device does not distinguish the
+letter O from the digit 0, that is the letter O followed by the digit
+0).  You can specify any compiler option or set of options here, not
+just optimizer options.  These options are appended to the list of all
+other compiler options, so you should be able to override almost any
+compiler option prepared by Configure.  (Obviously this depends on how
+the compiler treats conflicting options, but most seem to go with the
+last value specified on the command line).
+
+You should also allow for the XXX_cflags variable to be overridden on the
+command line.
+
+See the vos.sh hints file for an extended example of these techniques.
+
+=head1 Hint file tricks
+
+=head2 Printing critical messages
+
+[This is still experimental]
+
+If you have a *REALLY* important message that the user ought to see at
+the end of the Configure run, you can store it in the file
+'config.msg'.  At the end of the Configure run, Configure will display
+the contents of this file.  Currently, the only place this is used is
+in Configure itself to warn about the need to set LD_LIBRARY_PATH if
+you are building a shared libperl.so.
+
+To use this feature, just do something like the following
+
+	$cat <<EOM  | $tee -a ../config.msg >&4
+
+    This is a really important message.  Be sure to read it
+    before you type 'make'.
+    EOM
+
+This message will appear on the screen as the hint file is being
+processed and again at the end of Configure.
+
+Please use this sparingly.
+
+=head2 Propagating variables to config.sh
+
+Sometimes, you want an extra variable to appear in config.sh.  For
+example, if your system can't compile toke.c with the optimizer on,
+you can put
+
+    toke_cflags='optimize=""'
+
+at the beginning of a line in your hints file.  Configure will then
+extract that variable and place it in your config.sh file.  Later,
+while compiling toke.c, the cflags shell script will eval $toke_cflags
+and hence compile toke.c without optimization.
+
+Note that for this to work, the variable you want to propagate must
+appear in the first column of the hint file.  It is extracted by
+Configure with a simple sed script, so beware that surrounding case
+statements aren't any help.
+
+By contrast, if you don't want Configure to propagate your temporary
+variable, simply indent it by a leading tab in your hint file.
+
+For example, prior to 5.002, a bug in scope.c led to perl crashing
+when compiled with -O in AIX 4.1.1.  The following "obvious"
+workaround in hints/aix.sh wouldn't work as expected:
+
+    case "$osvers" in
+	4.1.1)
+    scope_cflags='optimize=""'
+	;;
+    esac
+
+because Configure doesn't parse the surrounding 'case' statement, it
+just blindly propagates any variable that starts in the first column.
+For this particular case, that's probably harmless anyway.
+
+Three possible fixes are:
+
+=over
+
+=item 1
+
+Create an aix_4_1_1.sh hint file that contains the scope_cflags
+line and then sources the regular aix hints file for the rest of
+the information.
+
+=item 2
+
+Do the following trick:
+
+    scope_cflags='case "$osvers" in 4.1*) optimize=" ";; esac'
+
+Now when $scope_cflags is eval'd by the cflags shell script, the
+case statement is executed.  Of course writing scripts to be eval'd is
+tricky, especially if there is complex quoting.  Or,
+
+=item 3
+
+Write directly to Configure's temporary file UU/config.sh.
+You can do this with
+
+    case "$osvers" in
+	4.1.1)
+	echo "scope_cflags='optimize=\"\"'" >> UU/config.sh
+	scope_cflags='optimize=""'
+	;;
+    esac
+
+Note you have to both write the definition to the temporary
+UU/config.sh file and set the variable to the appropriate value.
+
+This is sneaky, but it works.  Still, if you need anything this
+complex, perhaps you should create the separate hint file for
+aix 4.1.1.
+
+=back
+
+=head2 Call-backs
+
+=over 4
+
+=item Compiler-related flags
+
+The settings of some things, such as optimization flags, may depend on
+the particular compiler used.  For example, consider the following:
+
+    case "$cc" in
+    *gcc*)  ccflags="$ccflags -posix"
+	    ldflags="$ldflags -posix"
+	    ;;
+    *)      ccflags="$ccflags -Xp -D_POSIX_SOURCE"
+	    ldflags="$ldflags -Xp"
+	    ;;
+    esac
+
+However, the hints file is processed before the user is asked which
+compiler should be used.  Thus in order for these hints to be useful,
+the user must specify  sh Configure -Dcc=gcc on the command line, as
+advised by the INSTALL file.
+
+For versions of perl later than 5.004_61, this problem can
+be circumvented by the use of "call-back units".  That is, the hints
+file can tuck this information away into a file UU/cc.cbu.  Then,
+after Configure prompts the user for the C compiler, it will load in
+and run the UU/cc.cbu "call-back" unit.  See hints/solaris_2.sh for an
+example.
+
+=item Future status
+
+I hope this "call-back" scheme is simple enough to use but powerful
+enough to deal with most situations.  Still, there are certainly cases
+where it's not enough.  For example, for aix we actually change
+compilers if we are using threads.
+
+I'd appreciate feedback on whether this is sufficiently general to be
+helpful, or whether we ought to simply continue to require folks to
+say things like "sh Configure -Dcc=gcc -Dusethreads" on the command line.
+
+=back
+
+Have the appropriate amount of fun :-)

+# The gross features should work with versions going back to 2.nil but

+# DGUX is an SVR4 derivative.  It ships with gcc as the standard
+# compiler.  Since version 3.0 it has shipped with Perl 4.036
+# installed in /usr/bin, which is kind of neat.  Be careful when you
+# install that you don't overwrite the system version, though (by
+# answering yes to the question about installing perl as /usr/bin/perl),
+# as it would suck to try to get support if the vendor learned that you
+# were physically replacing the system binaries.
+#
+# -Roderick Schertler <roderick@argon.org>
+
+# The standard system compiler is gcc, but invoking it as cc changes its
+# behavior.  I have to pick one name or the other so I can get the
+# dynamic loading switches right (they vary depending on this).  I'm
+# picking gcc because there's no way to get at the optimization options
+# and so on when you call it cc.

+# A: Yes.  There are two MPE problems here.  The 'undef' functions exist on MPE,
+# but are merely dummy routines that return ENOTIMPL or ESYSERR.  Since they're
+# useless, let's just tell Perl to avoid them.  Also, a few data items are
+# 'undef' because while they may exist in structures, they are uninitialized.
+#
+# The 'define' cases are a bit weirder.  MPE has a libc.a, libc.sl, and two
+# special kernel shared libraries, /SYS/PUB/XL and /SYS/PUB/NL.  Much of what
+# is in libc.a is duplicated within XL and NL, so when we created libc.sl, we
+# omitted the duplicated functions.  Since Configure end ups scanning libc.sl,
+# we need to 'define' the functions that had been removed.
+#

+# THE MALLOC STORY
+######################################################################
+# 1994:
+# the simple program `for ($i=1;$i<38771;$i++){$t{$i}=123}' fails
+# with Larry's malloc on NS 3.2 due to broken sbrk()
+#
+# setting usemymalloc='n' was the solution back then. Later came
+# reports that perl would run unstable on 3.2:
+#
+# 1996:
+# From about perl5.002beta1h perl became unstable on the
+# NeXT. Intermittent coredumps were frequent on 3.2 OS. There were
+# reports, that the developer version of 3.3 didn't have problems, so it
+# seemed pretty obvious that we had to work around an malloc bug in 3.2.
+# This hints file reflects a patch to perl5.002_01 that introduces a
+# home made sbrk routine (remember, NeXT's sbrk _never_ worked). This
+# sbrk makes it possible to run perl with its own malloc. Thanks to
+# Ilya who showed me the way to his sbrk for OS/2!!
+#
+# The whole malloc desaster lead to a failing gdbm test. It is far
+# beyond my understanding, why GDBM_File breaks with the "fix", but in
+# general I consider it better to have a working perl with broken GDBM
+# than no perl at all.
+#
+# So, this hintsfile is using perl's malloc. If you want to turn
+# perl's malloc off, you need to remove '-DUSE_PERL_SBRK'
+# from the ccflags and set usemymalloc to 'n'.
+#
+# 1997:
+# From perl5.003_22 the malloc bug has no impact any more. We can run
+# a perl without a special sbrk. Apparently Chip Salzenberg, the hero
+# of 5.004 anyway, earned another trophy during Australien Open.
+#
+# use the following two lines to enable USE_PERL_SBRK. Try this if you
+# encounter intermittent core dumps:
+#ccflags='-DUSE_NEXT_CTYPE -DUSE_PERL_SBRK'
+#usemymalloc='y'
+# use the following two lines if you have perl5.003_22 or better and
+# do not encounter intermittent core dumps.

+# QNX hints
+#
+# Most of the hints in this file are for QNX4, which needed
+# more help. The QNX6 hints are located toward the bottom.
+#
+# perl-5.7.3 passes all tests under QNX4.24G
+#  Watcom 10.6 with Beta/970211.wcc.update.tar.F
+#  socket3r.lib Nov21 1996.
+# perl-5.7.3 fails 2 known tests under QNX6.1.0
+#
+# As with many unix ports, this one depends on a few "standard"
+# unix utilities which are not necessarily standard for QNX4.
+#
+# /bin/sh  This is used heavily by Configure and then by
+#          perl itself. QNX4's version is fine, but Configure
+#          will choke on the 16-bit version, so if you are
+#          running QNX 4.22, link /bin/sh to /bin32/ksh
+# ar       This is the standard unix library builder.
+#          We use wlib. With Watcom 10.6, when wlib is
+#          linked as "ar", it behaves like ar and all is
+#          fine. Under 9.5, a cover is required. One is
+#          included in ../qnx
+# nm       This is used (optionally) by configure to list
+#          the contents of libraries. I will generate
+#          a cover function on the fly in the UU directory.
+# cpp      Configure and perl need a way to invoke a C
+#          preprocessor. I have created a simple cover
+#          for cc which does the right thing. Without this,
+#          Configure will create its own wrapper which works,
+#          but it doesn't handle some of the command line arguments
+#          that perl will throw at it.
+# make     You really need GNU make to compile this. GNU make
+#          ships by default with QNX 4.23, but you can get it
+#          from quics for earlier versions.
+#----------------------------------------------------------------
+# Outstanding Issues for QNX4:
+#   There is no support for dynamically linked libraries in
+#   QNX4.
+#
+#   If you wish to compile with the Socket extension, you need
+#   to have the TCP/IP toolkit, and you need to make sure that
+#   -lsocket locates the correct copy of socket3r.lib. Beware
+#   that the Watcom compiler ships with a stub version of
+#   socket3r.lib which has very little functionality. Also
+#   beware the order in which wlink searches directories for
+#   libraries. You may have /usr/lib/socket3r.lib pointing to
+#   the correct library, but wlink may pick up
+#   /usr/watcom/10.6/usr/lib/socket3r.lib instead. Make sure
+#   they both point to the correct library, that is,
+#   /usr/tcptk/current/usr/lib/socket3r.lib.
+# 
+#   ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give
+#   the same results. cwd calls `fullpath -t`, so if you
+#   cd `fullpath -t` before running the test, it will
+#   pass.
+#
+#   lib/File/Find/taint.t will complain if '.' is in your
+#   PATH. The PATH test is triggered because cwd calls
+#   `fullpath -t`.
+#
+#   ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to
+#   the fact that the functionality to read back the non-blocking
+#   status of a socket is not implemented in QNX's TCP/IP. This
+#   has been reported to QNX and it may work with later versions
+#   of TCP/IP.
+#
+# Older issues:
+#   lib/posix.t test failed on test 17 because acos(1) != 0.
+#      Resolved in 970211 Beta
+#   lib/io_udp.t test hangs because of a bug in getsockname().
+#      Fixed in latest BETA socket3r.lib
+#----------------------------------------------------------------
+# Outstanding Issues for QNX6:
+#  The following tests are still failing as of 5.7.3:
+#
+#   op/sprintf.........................FAILED at test 91
+#   lib/Benchmark......................FAILED at test 26
+#
+# This is due to a bug in the C library's printf routine.
+# printf("'%e'", 0. ) produces '0.000000e+0', but ANSI requires
+# '0.000000e+00'. QNX has acknowledged the bug and it should be
+# fixed in 6.2.0.

+# -You cannot optimize with genuine sco cc (miniperl core dumps),
+#  so Perl is faster if compiled with gcc.
+# -Even optimized for speed, gcc generated code is smaller (!!!)
+# -gcc is free
+# -I use ld to link which is distributed with the core OS distribution, so you
