Hi Paul,
I uploaded a bzipped copy of
  /usr/include/sys
  /usr/include/cygwin

on
  http://matzeri.altervista.org/works/include/

for what I see <sys/time> includes <sys/types.h> but
none of the two include directly <sys/select.h>

The chain seems:
sys/time.h:#include <cygwin/sys_time.h>
cygwin/sys_time.h:#include <sys/select.h>

Regards
Marco
