# Avoid bugs in AC_REQUIRE in Autoconf 2.63 and earlier. This
# definition is slower than the version in Autoconf 2.64, because it
# can only use interfaces that existed since 2.59; but it achieves the

# The following definitions arrange to use a compiler option
# -Werror=implicit-function-declaration in AC_CHECK_DECL, when the

# library functions in C mode, but not in C++ mode, which would cause
# Gnulib to omit a declaration and thus later produce an error in C++
# mode. As of clang 9.0, these "known" functions are identified through
# LIBBUILTIN invocations in the LLVM source file
# llvm/tools/clang/include/clang/Basic/Builtins.def.
# It's not possible to AC_REQUIRE the extra tests from AC_CHECK_DECL,

# Use '""', not '<>', so that the /// cannot be confused with a C99 comment.

Suppress extern inline with HP-UX cc, as it appears to be broken; see
<http://lists.gnu.org/archive/html/bug-texinfo/2013-02/msg00030.html>.
<https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
Suppress extern inline with Sun C in standards-conformance mode, as it
mishandles inline functions that call each other. E.g., for 'inline void f
(void) { } inline void g (void) { f (); }', c99 incorrectly complains
'reference to static identifier "f" in extern inline function'.
This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
This bug was observed with Oracle Developer Studio 12.6
(Sun C 5.15 SunOS_sparc 2017/05/30).
Suppress the use of extern inline on Apple's platforms, as Libc at least
through Libc-825.26 (2013-04-09) is incompatible with it; see, e.g.,
<http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00023.html>.
Perhaps Apple will fix this some day. */
Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
on configurations that mistakenly use 'static inline' to implement
functions or macros in standard C headers like <ctype.h>. For example,
if isdigit is mistakenly implemented via a static inline function,
a program containing an extern inline function that calls isdigit
may not work since the C standard prohibits extern inline functions
from calling static functions (ISO C 99 section 6.7.4.(3).
This bug is known to occur on:
OS X 10.8 and earlier; see:
https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
DragonFly; see
http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
FreeBSD; see:
https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
Assume DragonFly and FreeBSD will be similar.
GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
inline semantics, unless -fgnu89-inline is used. It defines a macro
__GNUC_STDC_INLINE__ to indicate this situation or a macro
__GNUC_GNU_INLINE__ to indicate the opposite situation.
GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
semantics but warns, unless -fgnu89-inline is used:
warning: C99 inline functions are not supported; using GNU89
warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

dnl
dnl This file can can be used in projects which are not available under
dnl the GNU General Public License or the GNU Library General Public
dnl License but which still want to provide support for the GNU gettext
dnl functionality.
dnl Please note that the actual code of the GNU gettext library is covered
dnl by the GNU Library General Public License, and the rest of the GNU
dnl gettext package package is covered by the GNU General Public License.
dnl They are *not* in the public domain.
dnl Authors:
dnl Ulrich Drepper <drepper@cygnus.com>, 1995-2000.
dnl Bruno Haible <haible@clisp.cons.org>, 2000-2006, 2008-2010.
dnl Macro to add for using GNU gettext.
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
dnl default (if it is not specified or empty) is 'no-libtool'.
dnl INTLSYMBOL should be 'external' for packages with no intl directory,
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
dnl If INTLSYMBOL is 'use-libtool', then a libtool library
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
dnl depending on --{enable,disable}-{shared,static} and on the presence of
dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
dnl $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored. If NEEDSYMBOL is specified and is
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
dnl INTLDIR is used to find the intl libraries. If empty,
dnl the value '$(top_builddir)/intl/' is used.
dnl
dnl The result of the configuration is one of three cases:
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
dnl and used.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 2) GNU gettext has been found in the system's C library.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 3) No internationalization, always use English msgid.
dnl Catalog format: none
dnl Catalog extension: none
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
dnl The use of .gmo is historical (it was needed to avoid overwriting the
dnl GNU format catalogs when building on a platform with an X/Open gettext),
dnl but we keep it in order not to force irrelevant filename changes on the
dnl maintainers.
