From c12d372d263309e2ee81efda713096ea9e62a759 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 17 Oct 2019 20:51:44 -0600 Subject: [PATCH] Check for sigprocmask in common.m4 I noticed that gdbsupport uses HAVE_SIGPROCMASK, but common.m4 does not check for it. This means that gdbserver may not compile some gdbsupport code properly. This patch fixes this error. gdb/ChangeLog 2019-10-23 Tom Tromey * configure: Rebuild. * configure.ac: Don't check for sigprocmask. * gdbsupport/common.m4 (GDB_AC_COMMON): Check for sigprocmask. gdb/gdbserver/ChangeLog 2019-10-23 Tom Tromey * configure, config.in: Rebuild.
