Code: In short - Wine uses gcc to create it's dlls. And gcc has no concepts of .def file. So it's compiler dependent. Ok, I can live with it, it's not that big deal, just pain in the head. > That's what native (windows) does. You should ask MS why they export the same function from several dlls. I would say they're insane but I'm discovering now they have done a great work although they're greedy and selfish but they still have brains that really work! Another bad fact that I have to deal with it and accept it as it is, thanks Bill to make things harder to be understood. I'm messing with the ADVAPI32.DLL and I think I make some improvements.
