Hi,
for a start in supporting Cygwin, I created this patch. It doesn't
error out just because _WIN32 is not defined and the new _cygwin.h file
(which will probably get a lot more to do later on) just makes sure that
_mingw.h does not define POSIX types.
Additionally, I changed vadefs.h so that it doesn't test for _WIN32
at all. After all, it includes _mingw.h which runs this test anyway.
Hope that's ok,
Corinna
mingw-w64-headers/ChangeLog:
* configure.ac (BASEHEAD_LIST): Add _cygwin.h.
* configure: Regenerate.
mingw-w64-headers/crt/ChangeLog:
* _cygwin.h: New file.
* _mingw.h.in: Include _cygwin.h when building a Cygwin application.
Allow building Cygwin applications even though _WIN32 isn't defined.
* vadefs.h: Drop test for _WIN32 since it's done in _mingw.h.
