--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This might still not be a GCC bug.

Note the first warning is definitely not a GCC bug and should be fixed in the
sources:
1.15.0/xkb/xkbInit.c:690:22: warning: type of 'XkbDfltAccessXOptions' does not
match original declaration [enabled by default]
 extern unsigned char XkbDfltAccessXOptions;
                      ^
/var/tmp/portage/x11-base/xorg-server-1.15.0/work/xorg-server-1.15.0/xkb/xkbAccessX.c:58:16:
note: previously declared here
 unsigned short XkbDfltAccessXOptions =
                ^

----- CUT ----
You are going to have to try to reduce the testcase.  Also just this one file
is not enough to reproduce the issue as this happens only with -flto it seems.
