Develop .h for Wine by looking Microsoft Platform SDK

[Pau Garcia i Quiles]

Hello,

How legal (if at all) would be to develop a header file by looking  
reading the corresponding header file from the Microsoft Platform SDK  
and adapting it to gcc (removing MSVC stuff, etc)?

I'm interested in supporting annotations[*] and before I start  
deducting everything from MSDN documentation, I'd like to know if  
there is a fast track.
