Hi, We've got a couple of bug reports saying that gettext's libintl doesn't work when it was compiled on Mac OS X >= 10.7 targetting 10.6, because of missing PTHREAD_RECURSIVE_MUTEX_INITIALIZER definition:
<http://savannah.gnu.org/bugs/?37844> <http://lists.gnu.org/archive/html/bug-gettext/2013-05/msg00007.html> According to the report, other projects seem to have added a work around for this, perhaps good to add the same check to Gnulib. Patch attached. It compiles fine on 10.8, but not actually tested on 10.6. It would be nice if anyone could test the compiled binary on 10.6. Regards, -- Daiki Ueno
