Sorry, I don't quite understand: these defines are present only when compiling user32. Now, how do we know what defines MS uses to compile their user32? How can this ever be relevant to us?
We know because the defines are used in the Microsoft headers for the dllimport stuff. We don't need them for that purpose, but we could still use them for something else, like optimizations.
