Pick up gettext patch for pthread_sigmask build on mingw32 Fixes #1272. Signed-off-by: Alexey Neyman <stilor@att.net>
2020-01-22 21:34:04 +00:00
commit 64e905db05c32792c3f0e77ce271f65e77980a92
Author: Bruno Haible <bruno@clisp.org>
Date: Sat May 18 14:36:33 2019 +0200
pthread_sigmask: Fix compilation error with --enable-threads=windows.
Reported by Tim Rühsen in
<https://lists.gnu.org/archive/html/bug-gnulib/2018-01/msg00018.html>
and Michele Locati in
<https://lists.gnu.org/archive/html/bug-gettext/2019-04/msg00057.html>.
* m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Revert change from
2015-06-01. Test whether pthread_sigmask is a macro, regardless of
$LIBMULTITHREAD. Consider it regardless whether module 'threadlib' is
in use and regardless which threads API is chosen.
[Dropped ChangeLog; adjusted the paths to apply to gettext; regenerate.]
