But it breaks on cygwin.

Cygwin also has <io.h>, but this redefinition of pipe breaks cygwin's
<unistd.h>. You need to further restrict this definition to native windows
environments.
In file included from /usr/include/unistd.h:4,
from ../../gltests/test-poll.c:39:
/usr/include/sys/unistd.h:127: error: parse error before numeric constant
make[4]: *** [test-poll.o] Error 1
$ head -n 127 /usr/include/sys/unistd.h | tail -n1
int _EXFUN(pipe, (int __fildes[2] ));
where _EXFUN results in 'pipe(int __fildes[2])'.
