Subject: Fix Readline 8.1 build on mingw
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4cbf332613a833e214e825817093b945c6a38bbd;p=thirdparty%2Fbinutils-gdb.git

Fix Readline 8.1 build on mingw

The mingw build fails with Readline 8.1, because sigprocmask is called
unconditionally.  This patch adds the missing check for
HAVE_POSIX_SIGNALS.

I reported this upstream here:

	* readline/signals.c (_rl_handle_signal): Add missing check for
	HAVE_POSIX_SIGNALS.
