timestamp: Tue 2013-09-24 20:44:34 -0700
message:
  Merge from gnulib.
  
  This incorporates:
  2013-09-24 manywarnings: enable nicer gcc warning messages
  2013-09-23 warnings: port --enable-gcc-warnings to Solaris Studio 12.3
  2013-09-21 timespec: use the new TIMESPEC_RESOLUTION elsewhere
  * configure.ac (WERROR_CFLAGS): Omit -fdiagnostics-show-option
  and -funit-at-a-time, since manywarnings does that for us now.
