one more legal/protocol question

[Misha Koshelev]

Dear All:

I may be mistaken, but it appears that the constants used for D3DX Mesh
Options:
http://msdn.microsoft.com/en-us/library/bb205746%28v=VS.85%29.aspx

are not yet present in Wine.

For example, in the main Wine source directory the command:

find . -name \*.h -exec grep D3DXMESH_32BIT {} \;

does not return any results.

I would like to add these constants.

My question:
Can I simply 
1) look at the relevant DirectX 9 Microsoft .h files and add the
constants (rewriting of course not copy paste) from there?
or
2) do I have to do something more complicated?

Thank you
Misha
