I will enhance the log message, no problem here. Should I consider the 
referenced patch as being applied (so that I should base my patch on it)?

The tests will be a problem, because I don't have the Windows machine as a 
reference. Also `make test` fails on DirectX tests for me because of r600 
driver bug...

When I write CreateSurface tests (for various interfaces), is there a way for 
me to run the tests on Windows? I have a Windows XP machine at work.

Thanks,
Oldrich.
