8e43b2c6 - Update gettext-runtime files from gnulib.

Update gettext-runtime files from gnulib. * Makefile.am (distcheck-hook): Check also flexmember.m4, flexmember.h. * gettext-runtime/intl/Makefile.in (SOURCES): Add flexmember.h. * gettext-runtime/intl/flexmember.h: New file, from gnulib. * gettext-runtime/intl/localcharset.c: * localcharset.c (relocate2): Define fallback. (get_charset_aliases): Invoke relocate2 instead of relocate. Free the allocated memory. * localcharset.c (WINDOWS_NATIVE): Don't define on Cygwin. * localcharset.c (locale_charset) [WINDOWS_NATIVE]: Don't use the return value from setlocale if it would lead to a buffer overrun. * gettext-runtime/intl/localename.c: * localename.c [__CYGWIN__]: Include <langinfo.h>, since this is where NL_LOCALE_NAME is defined. * localename.c (WINDOWS_NATIVE): Don't define on Cygwin. * localename.c (gl_locale_name_thread_unsafe): Add clause for Cygwin. * localename.c (struct hash_node): Use FLEXIBLE_ARRAY_MEMBER. * gettext-runtime/intl/lock.c: * lock.c: On glibc systems without PTHREAD_RWLOCK_WRITER_NONRECURSIVE_INITIALIZER_NP, use the fallback implementation of rwlocks. * lock.c [USE_POSIX_THREADS] (glthread_rwlock_init_for_glibc): New function. [USE_POSIX_THREADS] (glthread_rwlock_rdlock_multithreaded): Update comment. [USE_PTH_THREADS]: New implementation of rwlocks. [USE_WINDOWS_THREADS] (glthread_rwlock_rdlock_func): Prefer writers over readers. * gettext-runtime/intl/lock.h: * lock.h (pthread_rwlockattr_setkind_np): Don't declare weak on non-glibc platforms. * lock.h: On glibc systems without PTHREAD_RWLOCK_WRITER_NONRECURSIVE_INITIALIZER_NP, use the fallback implementation of rwlocks. * lock.h [USE_POSIX_THREADS_WEAK]: Declare also pthread_rwlockattr_init, pthread_rwlockattr_setkind_np, pthread_rwlockattr_destroy weak. * lock.h [USE_POSIX_THREADS]: Test HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. Use a different implementation of rwlock initialization on glibc systems without HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. Use a different implementation of rwlocks altogether on non-glibc systems without HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. [USE_PTH_THREADS]: Use a different implementation of rwlocks altogether. * gettext-runtime/intl/relocatable.c: * relocatable.c (relocate2): New function. * relocatable.c (relocate): Assume pathname is non-NULL. Use ISSLASH macro consistently. Avoid dangerous string concatenation idiom. * gettext-runtime/intl/relocatable.h: * relocatable.h (relocate2): New declaration/macro. * gettext-runtime/intl/vasnprintf.c, gettext-runtime/libasprintf/vasnprintf.c: * vasnprintf.c (FALLTHROUGH): New macro. Use it whenever one switch case falls through into the next. * vasnprintf.c (USE_MSVC__SNPRINTF): New macro. Everywhere, use !HAVE_SNPRINTF_RETVAL_C99 || USE_MSVC__SNPRINTF instead of !HAVE_SNPRINTF_RETVAL_C99. * vasnprintf.c (VASNPRINTF): Move comment down past two cpp directives, so that it takes effect once again. This is clearly not a proper change, and I will revert it once this bug is fixed: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77817 * vasnprintf.c (IF_LINT): Treat GCC_LINT like lint. * gettext-runtime/intl/verify.h: * verify.h (verify) [!__GNUC__]: Use shorter albeit meaningless string to bypass silly compiler limits. * verify.h (assume): Treat GCC_LINT like lint. * gettext-runtime/intl/xsize.h: Update. * gettext-runtime/m4/Makefile.am (EXTRA_DIST): Add flexmember.m4. * gettext-runtime/m4/extern-inline.m4: Update. * gettext-runtime/m4/fcntl-o.m4: Update. * gettext-runtime/m4/flexmember.m4: New file, from gnulib. * gettext-runtime/m4/glibc2.m4: Update. * gettext-runtime/m4/glibc21.m4: Update. * gettext-runtime/m4/intdiv0.m4: Update. * gettext-runtime/m4/intl.m4 (AM_INTL_SUBDIR): Require AC_C_FLEXIBLE_ARRAY_MEMBER. * gettext-runtime/m4/intmax.m4: Update. * gettext-runtime/m4/inttypes-pri.m4: Update. * gettext-runtime/m4/inttypes_h.m4: Update. * gettext-runtime/m4/lock.m4 (gl_LOCK): Invoke gl_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. * gettext-runtime/m4/longlong.m4: Update. * gettext-runtime/m4/printf-posix.m4: Update. * gettext-runtime/m4/progtest.m4: Update. * gettext-runtime/m4/size_max.m4: Update. * gettext-runtime/m4/stdint_h.m4: Update. * gettext-runtime/m4/threadlib.m4 (gl_THREADLIB_BODY): Don't set PTHREAD_IN_USE_DETECTION_HARD if configuring on Solaris 10 or newer. Reported by Peter Felecan at <https://savannah.gnu.org/bugs/?32087>. * gettext-runtime/m4/uintmax_t.m4: Update. * gettext-runtime/m4/visibility.m4: Update. * gettext-runtime/m4/wchar_t.m4: Update. * gettext-runtime/m4/xsize.m4: Update. * gettext-runtime/tests/test-lock.c: * test-lock.c: On Mac OS X, use named semaphores, not unnamed semaphores. (USE_NAMED_SEMAPHORE, USE_UNNAMED_SEMAPHORE): New macros. (atomic_int_semaphore): New macro. * test-lock.c (USE_SEMAPHORE): Don't set if <semaphore.h> does not exist. * test-lock.c (USE_SEMAPHORE): New constant. (struct atomic_int, init_atomic_int, get_atomic_int_value, set_atomic_int_value) [USE_SEMAPHORE]: Define using a POSIX semaphore. Suggested by Torvald Riegel <triegel@redhat.com>.
