I just checked and there's no difference in the header files at all.

The w32api headers are system headers so -isystem rather than -idirafter should show a better result without requiring any of the source file changes. Especially having to define _WIN32 in winlean.h and winsup.h looks pretty wrong. I would also like to keep the ifndef/define brackets in the headers since #ifndef _CYGWIN_IF_H_ #define _CYGWIN_IF_H_ can be tested for in other headers while #pragma once can not.
