--- Comment #3 from Sergey Isakov isakov-sl@bk.ru --- There was a compilation with two stages wine64 and then wine32. I think headers may somehow cached and so i386 compilation became wrong. Don't know exactly. It seems not good idea to define symbols in two headers, one system and second internal for wine.
