These days there is a 64bit version of mingw (mingw64 or so it is called). They must have patches to add the calling convention to gcc now. I'm not sure what the status is on merging the changes back but I think nothing forbids you from building gcc from their sources. I have no idea whether having the calling convention is enough for Wine.
