[PATCH] turn on timercmp, et al, for Cygwin

[Christopher Faylor]

It looks like persistence pays off.  Someone has been sending multiple messages
to the cygwin mailing list complaining that timercmp was "broken" on cygwin.

What he meant by "broken" was "unimplemented".  The minor patch below turns
on the timercmp code for both RTEMS and Cygwin.

Should this just be on by default?  It doesn't add any code anywhere.  It
does pollute the namespace a little, of course.

I've checked this in.
