Hi,
Please write a test for this and add it to dlls/ddraw/tests/ddrawmodes.c It 
might happen that Windows returns an error in this situation. I think we 
already have a test that shows that DDSCL_FULLSCREEN without 
DDSCL_EXCLUSIVE(and vice versa) is not permitted, so I think setting 
DDSCL_EXCLUSIVE in the if case is wrong.

Also please use the code layout of the surrounding code.
