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.
