Dave Airlie (cc'd) did some work previously to allow things to be compiled with libxcb 1.11/1.12, mainly by ifdef'ing certain code with HAVE_DRI3_MODIFIERS so that it would compile, but without the extra features that xcb 1.13+ provides. See commit 7aeef2d4efdc809a698e "dri3: allow building against older xcb (v3)" for that.

Pushed it, was building on old Ubuntu yesterday and forgot to actually
push it back out.
