As mentioned elsewhere one could avoid this, and just use drm.h to
manage the approapriate types (uint32_t vs __u32 and so on).

I fear that this one is a particular example of a nasty legacy from
the UMS days. The file is available/provided in very old mesa versions
and at the very same time mesa requires via_drm.h. So I would kindly
ask that you:

 - Grab the libdrm userspace package, and apply a similar change.
 - Rebuild/install the above.
 - Fetch mesa 7.11, and try building the via dri module. Ideally
things will continue to build, alternatively we might need to add
another/additional guard for this include.

Thanks
Emil
