its similiar to https://bugs.gentoo.org/show_bug.cgi?id=402285 :
using -O2 instead -O3 solves the build problem.

Seems like a bug in your brand new compiler, since the code appears correct.
http://cgit.freedesktop.org/xorg/xserver/tree/dix/main.c?id=xorg-server-1.11.4#n167
shows the code in question is:
for (i=1; i<MAXCLIENTS; i++)
clients[i] = NullClient;
and include/dix.h defines that array as:
extern _X_EXPORT ClientPtr clients[MAXCLIENTS];
