+
+ c-ctype, regex, verify: port to gcc -std=c90 -pedantic
+ Avoid constructions that are rejected by gcc -std=c90 -pedantic.
+ This fixes a porting bug I recently reintroduced in regex, and
+ some other instances that I discovered while testing the fix.
+ * lib/c-ctype.h [__STRICT_ANSI__]: Avoid ({ ... }).
+ * lib/regcomp.c (utf8_sb_map) [__STRICT_ANSI__]: Avoid [0 ... N] = E.
+ * lib/regex_internal.h [!_LIBC && GNULIB_LOCK]: Do not use a macro
+ with an empty argument if this is a pedantic pre-C99 GCC.
+ * lib/verify.h: Do not use _Static_assert if this is a pedantic
+ pre-C11 GCC.
+
+ regex: adapt to locking regime instead of depending on pthread
+ Instead of depending on pthread, adapt to whatever thread
+ modules are in use. Problem reported by Ludovic Courtès in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00082.html>
+ and by Mats Erik Andersson in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00100.html>.
+ * lib/regex_internal.h (lock_define, lock_init, lock_fini):
+ Support either the 'lock' module, or the 'pthread' module, or
+ no module.
+ (lock_lock, lock_unlock): New macros.
+ * lib/regexec.c (regexec, re_search_stub): Use the new macros.
+ * modules/lock, modules/pthread (configure.ac): Add module indicator.
+ * modules/regex (Depends-on): Remove pthread.

+
+ test-lchown, test-chown: also skip test if chown fails with EPERM
+ * tests/test-lchown.h (test_lchown): Add EPERM to the condition to
+ skip this test, to handle FAT file systems.
+ * tests/test-chown.h (test_chown): Likewise.

+
+ regex: fix dfa race in multithreaded uses
+ Problem reported by Ludovic Courtès in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00058.html>.
+ * lib/regex_internal.h (lock_define, lock_init, lock_fini):
+ New macros. All uses of __libc_lock_define, __libc_lock_init
+ changed to use the first two of these.
+ (__libc_lock_lock, __libc_lock_unlock): New macros, for
+ non-glibc platforms.
+ (struct re_dfa_t): Define the lock unconditionally.
+ * lib/regexec.c (regexec, re_search_stub): Remove some now-incorrect
+ '#ifdef _LIBC"s.
+ * modules/regex (Depends-on): Add pthread, if we use the
+ included regex.
+
+ * lib/regcomp.c: Do actions that are not needed for glibc,
+ but may be needed elsewhere.
+ (regfree, re_compile_internal): Destroy the lock.
+ (re_compile_internal): Check for lock-initialization failure.
+
+ malloca: port to compilers that reject size-zero arrays
+ This fixes a bug introduced in my previous patch.
+ * lib/malloca.c (struct preliminary_header): Use an int
+ rather than a character array of size int; that's simpler.
+ (struct header): Remove, replacing with ...
+ (union header): New type. This avoids the need for declaring a
+ character array of size zero, which is not allowed on some platforms.
+ All uses changed.

+
+ parse-datetime, tests: don't use "string" + int
+ Recent versions of 'clang' complain about C source code that
+ uses expressions of the form '"string literal" + integer',
+ I guess on the theory that it's confusing for readers who are
+ used to C++. On those grounds I suppose it's OK to make this
+ minor style change.
+ * lib/parse-datetime.y (parse_datetime):
+ * tests/test-fchdir.c (main):
+ * tests/test-snprintf-posix.h (test_function):
+ * tests/test-snprintf.c (main):
+ * tests/test-vasnprintf-posix.c (test_function):
+ * tests/test-vasnprintf.c (test_function):
+ * tests/test-vsnprintf.c (main):
+ * tests/unistdio/test-ulc-asnprintf1.h (test_function):
+ Rewrite '"str" + E' to '&"str"[E]'.

+ manywarnings: update for GCC 4.8.0
+ * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC):
+ Add -Waggressive-loop-optimizations, -Wreturn-local-addr, which
+ are new to GCC 4.8. Remove -Wformat=2, -Wmissing-format-attribute,
+ -Wmissing-noreturn, as they are duplicates of other warnings.
+ Remove -Wunreachable-code, as it is removed in GCC 4.8 and
+ was documented to be flaky in earlier versions of GCC.
+
+ spawn-tests, sys_socket-tests, sys_wait-tests: port to clang
+ * tests/test-spawn.c (main):
+ * tests/test-sys_socket.c (main):
+ * tests/test-sys_wait.c (main):
+ Don't have a switch value that isn't covered by a case.
+
+ getaddrinfo-tests: port --enable-gcc-warnings to clang
+ * tests/test-getaddrinfo.c (simple):
+ Avoid casts from looser to stricter-aligned pointers.
+
thread: port --enable-gcc-warnings to clang
* lib/glthread/thread.h [__clang__ && USE_POSIX_THREADS_WEAK]:
Include <signal.h>, to pacify a warning about pthread_sigmask.
