annotate lib/file-has-acl.c @ 17282:a4996fb12971

locale: port to Solaris 2.6 and 7 + GNU gettext * lib/locale.in.h: Just include_next <locale.h> when being invoked recursively. This prevents problems on Solaris 2.6 and 7 when combining the localename module with GNU gettext 0.18.2. Problem reported by Tom G. Christensen in <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00084.html>.
