  The <foo-config.h> headers are {xkb,dix,xorg}-config.h, and they
declare things like:
#define XF86VIDMODE 1
#define XINERAMA 1
#define DRI2 1

  But (most of) those are "moved" to xorg-server.h in an installed
sdk.

  I don't think the compiler parsing a few extra lines will have
much of an impact on compile time. And still, if one would need
to choose to have the compile time increase by 1% but make it
easier to manage the sources, it would be preferable.

  About those:
#define FEATURE 1
I think they should also be reworked to have enough fallbacks/stubs
to not cause a failure due to things like missing symbols. The
driver should be compiled with the proper sdk headers, but that is
not always the case...
