+       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.
