- # Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is
- # useless:
- # - It returns the empty string when LANG is set to a locale of the
- # form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
- # LC_CTYPE file.
- # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
- # the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
- # - The documentation says:
- # "... all code that calls BSD system routines should ensure
- # that the const *char parameters of these routines are in UTF-8
- # encoding. All BSD system functions expect their string
- # parameters to be in UTF-8 encoding and nothing else."
- # It also says
- # "An additional caveat is that string parameters for files,
- # paths, and other file-system entities must be in canonical
- # UTF-8. In a canonical UTF-8 Unicode string, all decomposable
- # characters are decomposed ..."
- # but this is not true: You can pass non-decomposed UTF-8 strings
- # to file system functions, and it is the OS which will convert
- # them to decomposed UTF-8 before accessing the file system.
- # - The Apple Terminal application displays UTF-8 by default.
- # - However, other applications are free to use different encodings:
- # - xterm uses ISO-8859-1 by default.
- # - TextEdit uses MacRoman by default.
- # We prefer UTF-8 over decomposed UTF-8-MAC because one should
- # minimize the use of decomposed Unicode. Unfortunately, through the
- # Darwin file system, decomposed UTF-8 strings are leaked into user
- # space nevertheless.
- # Then there are also the locales with encodings other than US-ASCII
- # and UTF-8. These locales can be occasionally useful to users (e.g.
- # when grepping through ISO-8859-1 encoded text files), when all their
- # file names are in US-ASCII.

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
- for FUNCTION which will then trigger a compiler warning containing
- the text of "literal string" anywhere that function is called, if
- supported by the compiler. If the compiler does not support this
- feature, the macro expands to an unused extern declaration.
-
- This macro is useful for marking a function as a potential
- portability trap, with the intent that "literal string" include
- instructions on the replacement function that should be used
- instead. However, one of the reasons that a function is a
- portability trap is if it has the wrong signature. Declaring
- FUNCTION with a different signature in C is a compilation error, so
- this macro must use the same type as any existing declaration so
- that programs that avoid the problematic FUNCTION do not fail to
- compile merely because they included a header that poisoned the
- function. But this implies that _GL_WARN_ON_USE is only safe to
- use if FUNCTION is known to already have a declaration. Use of
- this macro implies that there must not be any other macro hiding
- the declaration of FUNCTION; but undefining FUNCTION first is part
- of the poisoning process anyway (although for symbols that are
- provided only via a macro, the result is a compilation error rather
- than a warning containing "literal string"). Also note that in
- C++, it is only safe to use if FUNCTION has no overloads.
-
- For an example, it is possible to poison 'getline' by:
- - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
- [getline]) in configure.ac, which potentially defines
- HAVE_RAW_DECL_GETLINE
- - adding this code to a header that wraps the system <stdio.h>:
- #undef getline
- #if HAVE_RAW_DECL_GETLINE
- _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
- "not universally present; use the gnulib module getline");
- #endif
-
- It is not possible to directly poison global variables. But it is
- possible to write a wrapper accessor function, and poison that
- (less common usage, like &environ, will cause a compilation error
- rather than issue the nice warning, but the end result of informing
- the developer about their portability problem is still achieved):
- #if HAVE_RAW_DECL_ENVIRON
- static char ***rpl_environ (void) { return &environ; }
- _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
- # undef environ
- # define environ (*rpl_environ ())
- #endif

# 6. Blank lines, even if preceded by the prefix, do not appear
# within the FSF copyright statement.

+# This is a prologue that allows to run a perl script as an executable

+# On such systems, the usual invocation of an executable through execlp()
+# or execvp() fails with ENOEXEC if it is a script that does not start
+# with a #! line. The script interpreter mentioned in the #! line has
+# to be /bin/sh, because on GuixSD systems that is the only program that
+# has a fixed file name. The second line is essential for perl and is
+# also useful for editing this file in Emacs. The next two lines below
+# are valid code in both sh and perl. When executed by sh, they re-execute
+# the script through the perl program found in $PATH. The '-x' option
+# is essential as well; without it, perl would re-execute the script
+# through /bin/sh. When executed by perl, the next two lines are a no-op.

The FPU control word is under control of the application, i.e. it is
not required to be set either way by the ABI. (In fact, the i386 ABI
- http://refspecs.freestandards.org/elf/abi386-4.pdf page 3-12 = page 38
+ https://www.linux-mips.org/pub/linux/mips/doc/ABI/abi386-4.pdf page 3-12 = page 38
is not clear about it. But in any case, gcc treats the control word
like a "preserved" register: it emits code that assumes that the control
word is preserved across calls, and it restores the control word at the
end of functions that modify it.)

+ - It returns the empty string when LANG is set to a locale of the
+ form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
+ LC_CTYPE file.
+ - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+ the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+ - The documentation says:
+ "... all code that calls BSD system routines should ensure
+ that the const *char parameters of these routines are in UTF-8
+ encoding. All BSD system functions expect their string
+ parameters to be in UTF-8 encoding and nothing else."
+ It also says
+ "An additional caveat is that string parameters for files,
+ paths, and other file-system entities must be in canonical
+ UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+ characters are decomposed ..."
+ but this is not true: You can pass non-decomposed UTF-8 strings
+ to file system functions, and it is the OS which will convert
+ them to decomposed UTF-8 before accessing the file system.
+ - The Apple Terminal application displays UTF-8 by default.
+ - However, other applications are free to use different encodings:
+ - xterm uses ISO-8859-1 by default.
+ - TextEdit uses MacRoman by default.
+ We prefer UTF-8 over decomposed UTF-8-MAC because one should
+ minimize the use of decomposed Unicode. Unfortunately, through the
+ Darwin file system, decomposed UTF-8 strings are leaked into user
+ space nevertheless.
+ Then there are also the locales with encodings other than US-ASCII
+ and UTF-8. These locales can be occasionally useful to users (e.g.
+ when grepping through ISO-8859-1 encoded text files), when all their
+ file names are in US-ASCII.

+dnl This file is free software; the Free Software Foundation
+dnl gives unlimited permission to copy and/or distribute it,
+dnl with or without modifications, as long as this notice is preserved.
+
+dnl From Bruno Haible and Sam Steingold.
+
+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl will not run on SPARC CPUs and vice versa. They have different
+dnl instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl different argument passing and return conventions for C functions, and
+dnl although the instruction set of 'mips' is a large subset of the
+dnl instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl different sizes for the C types like 'int' and 'void *', and although
+dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl determine the endianness through preprocessor symbols:
+dnl - 'arm': test __ARMEL__.
+dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl assembly language source files use such instructions, you will
+dnl need to make the distinction.
+dnl - Speed of execution of the common instruction set is reasonable across
+dnl the entire family of CPUs. If you have assembly language source files
+dnl that are optimized for particular CPU types (like GNU gmp has), you
+dnl will need to make the distinction.

-dnl As a special exception to the GNU General Public License,
-dnl this file may be distributed as part of a program
-dnl that contains a configuration script generated by Autoconf, under
-dnl the same distribution terms as the rest of that program.
-
-dnl This file defines some "once only" variants of standard autoconf macros.
-dnl AC_CHECK_HEADERS_ONCE like AC_CHECK_HEADERS
-dnl AC_CHECK_FUNCS_ONCE like AC_CHECK_FUNCS
-dnl AC_CHECK_DECLS_ONCE like AC_CHECK_DECLS
-dnl AC_REQUIRE([AC_FUNC_STRCOLL]) like AC_FUNC_STRCOLL
-dnl The advantage is that the check for each of the headers/functions/decls
-dnl will be put only once into the 'configure' file. It keeps the size of
-dnl the 'configure' file down, and avoids redundant output when 'configure'
-dnl is run.
-dnl The drawback is that the checks cannot be conditionalized. If you write
-dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
-dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
-dnl empty, and the check will be inserted before the body of the AC_DEFUNed
-dnl function.
-
-dnl The original code implemented AC_CHECK_HEADERS_ONCE and AC_CHECK_FUNCS_ONCE
-dnl in terms of AC_DEFUN and AC_REQUIRE. This implementation uses diversions to
-dnl named sections DEFAULTS and INIT_PREPARE in order to check all requested
-dnl headers at once, thus reducing the size of 'configure'. It is known to work
-dnl with autoconf 2.57..2.62 at least . The size reduction is ca. 9%.
-
-dnl Autoconf version 2.59 plus gnulib is required; this file is not needed
-dnl with Autoconf 2.60 or greater. But note that autoconf's implementation of
-dnl AC_CHECK_DECLS_ONCE expects a comma-separated list of symbols as first
-dnl argument!

+dnl From Bruno Haible.
+dnl Inspired by
+dnl https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_rwlock_rdlock/2-2.c
+dnl by Intel Corporation.
+
+dnl Test whether in a situation where
+dnl - an rwlock is taken by a reader and has a writer waiting,
+dnl - an additional reader requests the lock,
+dnl - the waiting writer and the requesting reader threads have the same
+dnl priority,
+dnl the requesting reader thread gets blocked, so that at some point the
+dnl waiting writer can acquire the lock.
+dnl Without such a guarantee, when there a N readers and each of the readers
+dnl spends more than 1/Nth of the time with the lock held, there is a high
+dnl probability that the waiting writer will not get the lock in a given finite
+dnl time, a phenomenon called "writer starvation".
+dnl Without such a guarantee, applications have a hard time avoiding writer
+dnl starvation.
+dnl
+dnl POSIX:2017 makes this requirement only for implementations that support TPS
+dnl (Thread Priority Scheduling) and only for the scheduling policies SCHED_FIFO
+dnl and SCHED_RR, see
+dnl https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_rdlock.html
+dnl but this test verifies the guarantee regardless of TPS and regardless of
+dnl scheduling policy.
+dnl Glibc does not provide this guarantee (and never will on Linux), see
+dnl https://sourceware.org/bugzilla/show_bug.cgi?id=13701

+dnl gl_PTHREADLIB
+dnl -------------
+dnl Tests for the libraries needs for using the POSIX threads API.
+dnl Sets the variable LIBPTHREAD to the linker options for use in a Makefile.
+dnl Sets the variable LIBPMULTITHREAD, for programs that really need
+dnl multithread functionality. The difference between LIBPTHREAD and
+dnl LIBPMULTITHREAD is that on platforms supporting weak symbols, typically
+dnl LIBPTHREAD is empty whereas LIBPMULTITHREAD is not.
+dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
+dnl multithread-safe programs.
+dnl Defines the C macro HAVE_PTHREAD_API if (at least parts of) the POSIX
+dnl threads API is available.
+
dnl gl_THREADLIB
dnl ------------
dnl Tests for a multithreading library to be used.
dnl default is 'no', otherwise it is system dependent. In both cases, the user
dnl can change the choice through the options --enable-threads=choice or
dnl --disable-threads.
-dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
-dnl USE_PTH_THREADS, USE_WINDOWS_THREADS
+dnl Defines at most one of the macros USE_ISOC_THREADS, USE_POSIX_THREADS,
+dnl USE_ISOC_AND_POSIX_THREADS, USE_WINDOWS_THREADS.
+dnl The choice --enable-threads=isoc+posix is available only on platforms that
+dnl have both the ISO C and the POSIX threads APIs. It has the effect of using
+dnl the ISO C API for most things and the POSIX API only for creating and
+dnl controlling threads (because there is no equivalent to pthread_atfork in
+dnl the ISO C API).
dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
dnl libtool).
dnl symbols, typically LIBTHREAD is empty whereas LIBMULTITHREAD is not.
dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
dnl multithread-safe programs.
+dnl Since support for GNU pth was removed, $LTLIBTHREAD and $LIBTHREAD have the
+dnl same value, and similarly $LTLIBMULTITHREAD and $LIBMULTITHREAD have the
+dnl same value. Only system libraries are needed.

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+ for FUNCTION which will then trigger a compiler warning containing
+ the text of "literal string" anywhere that function is called, if
+ supported by the compiler. If the compiler does not support this
+ feature, the macro expands to an unused extern declaration.
+
+ _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+ attribute used in _GL_WARN_ON_USE. If the compiler does not support
+ this feature, it expands to empty.
+
+ These macros are useful for marking a function as a potential
+ portability trap, with the intent that "literal string" include
+ instructions on the replacement function that should be used
+ instead.
+ _GL_WARN_ON_USE is for functions with 'extern' linkage.
+ _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+ linkage.
+
+ However, one of the reasons that a function is a portability trap is
+ if it has the wrong signature. Declaring FUNCTION with a different
+ signature in C is a compilation error, so this macro must use the
+ same type as any existing declaration so that programs that avoid
+ the problematic FUNCTION do not fail to compile merely because they
+ included a header that poisoned the function. But this implies that
+ _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+ have a declaration. Use of this macro implies that there must not
+ be any other macro hiding the declaration of FUNCTION; but
+ undefining FUNCTION first is part of the poisoning process anyway
+ (although for symbols that are provided only via a macro, the result
+ is a compilation error rather than a warning containing
+ "literal string"). Also note that in C++, it is only safe to use if
+ FUNCTION has no overloads.
+
+ For an example, it is possible to poison 'getline' by:
+ - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+ [getline]) in configure.ac, which potentially defines
+ HAVE_RAW_DECL_GETLINE
+ - adding this code to a header that wraps the system <stdio.h>:
+ #undef getline
+ #if HAVE_RAW_DECL_GETLINE
+ _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+ "not universally present; use the gnulib module getline");
+ #endif
+
+ It is not possible to directly poison global variables. But it is
+ possible to write a wrapper accessor function, and poison that
+ (less common usage, like &environ, will cause a compilation error
+ rather than issue the nice warning, but the end result of informing
+ the developer about their portability problem is still achieved):
+ #if HAVE_RAW_DECL_ENVIRON
+ static char ***
+ rpl_environ (void) { return &environ; }
+ _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+ # undef environ
+ # define environ (*rpl_environ ())
+ #endif
+ or better (avoiding contradictory use of 'static' and 'extern'):
+ #if HAVE_RAW_DECL_ENVIRON
+ static char ***
+ _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
+ rpl_environ (void) { return &environ; }

-Subject: [PATCH] Fix PR gdb/23558: Use system's 'getcwd' when cross-compiling
- GDB
-
-This is a backport of a gnulib fix for the following bug:
-
- https://sourceware.org/bugzilla/show_bug.cgi?id=23558
-
-The problem reported there is about the replacement of 'getcwd' when
-cross-compiling GDB. With our current gnulib copy, the mechanism for
-deciding whether to use the system's 'getcwd' or gnulib's version is
-too simplistic and pessimistic, so when cross-compiling we always end
-up using gnulib's version, which has a limitation: it cannot handle
-the situation when the parent directory doesn't have read permissions.
-
-The solution is to backport the following gnulib commit:
-

-Subject: [PATCH] mkostemp, mkostemps: Fix compilation error in C++ mode on Mac
- OS X.
-
-Attempting to use the mkostemp module in gdb caused a build failure
-when using the C++ namespace feature, because mkostemp was not
-declared. On OS X, mkostemp is declared in unistd.h, so this patch
-extends the existing special case in stdlib.in.h to cover mkostemp and
-mkostemps.
-
-* lib/stdlib.in.h: Include <unistd.h> for mkostemp and mkostemps
-on OS X.
