I've set DRMSrcDir in my host.def to point to the CVS
drm tree:

  #define DRMSrcDir  /usr/local/src/fdo/drm

And I've deleted extras/drm/shared-core/drm.h just in case.
I made sure xc is getting drm.h from the CVS drm tree by
adding a "#warning" line there.

By the way, this bit of lib/GL/Mesa/shader/slang/Makefile looks wrong:

        $(RM) $@ unshared/$@
                $(CC) -c $(CCOPTIONS) $(THREADS_CFLAGS) $(ALLDEFINES)   $(CDEBUGFLAGS) $(CLIBDEBUGFLAGS) $(_NOOP_) $*.c -o unshared/$@
        $(RM) $@
                $(CC) -c $(CFLAGS) $(_NOOP_) $(SHLIBDEF) $(SHAREDCODEDEF) $(PICFLAGS) $*.c

I dunno how Imake ends up generating it, but it wont't work
because make invokes gcc with

  -o unshared/../../../../../lib/GL/mesa/shader/slang/slang_assemble_assignment.o"

instead of

  -o ../../../../../lib/GL/mesa/shader/slang/unshared/slang_assemble_assignment.o"
