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];
