AC_CYGWIN keeps saying 'no' although I'm running = configure from within bash and using cygwin latest from two days ago = (1.1.2).  This message seemed relevant.

Trying to compile a simple program like the following = fails... should be fairly similar to what autoconf is doing by my = reading of the macro.

#ifndef __CYGWIN__
#define __CYGWIN__ __CYGWIN32__
#endif

int main(int argc, char **argv) {
return __CYGWIN__;
}

//RTP-CBJONES/...//tmp $ gcc a.c
cpp: unrecognized option `-remap'
