I think the patch should be okay for code freeze, it's still a bug fix with
very low risk. We do want to test (not necessarily Wine tests) which d3dx9
versions require the flag. FWIW 3a5688a795532640bb32bd4c3e9961c6ab9f19fa
implies the behavior changed with d3dx9_37 for effect shaders.

Minor point, it would be nicer to use the D3DCOMPILE_ constant in the patch
instead.
