Here's the line at the top of sys/types.h causing these bugs:
#if defined (GO32) || defined (__MSDOS__) || defined (_WIN32)

it should be:
#if defined (GO32) || defined (__MSDOS__) || defined (_WIN32) ||
defined(__CYGWIN__)

I don't think there are more of these bugs, a grep for _WIN32
didn't reveal anything.

Anders
