[José Fonseca]

I can't commit to piglit. I get:

    $ git push
        Counting objects: 9, done.
        Delta compression using up to 2 threads.
        Compressing objects: 100% (5/5), done.
        Writing objects: 100% (5/5), 711 bytes, done.
        Total 5 (delta 4), reused 0 (delta 0)
        error: unable to create temporary sha1 filename ./objects/a8:
        File exists
        
        fatal: failed to write object
        error: unpack failed: unpacker exited with error code
        To ssh://git.freedesktop.org/git/piglit
         ! [remote rejected] HEAD -> master (n/a (unpacker error))
        error: failed to push some refs to
        'ssh://git.freedesktop.org/git/piglit'

Could someone with commit access please commit the attached patch.
There's a bunch of tests which are current failing on our setup because
the test machine is different from the build machine (which is building
piglit whenever something changes).

This would also make it easier to share binaries with other people. Esp
windows binaries are a pain to build due the requirements and the lack
of standard OSS packaging on windows.
