But the X server requires dri_interface.h and dri_sarea.h for AIGLX
and DRI2, remember? So, you have to install mesa first, unless you
want to put those headers somewhere else or keep a copy in the X
server.

The other drawback being that things can get out of sync. You
certainly know more about how that API holds up, but it seems like it
would break if, say, one of the API symbols in indirect_size.h existed
in mesa, but not in xserver. The other thing I was thinking would to
make a small library from the generated files and link that into libGL
and libglx.
