+       regex: adapt to locking regime instead of depending on pthread

+       <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.
