--- Comment #7 from Janne Blomqvist <jb at gcc dot gnu.org> ---
Issue is fixed on trunk (4.9). 

The question is whether it's useful to backport to 4.7 and 4.8. The previous
cygwin behavior, while perhaps surprising, isn't wrong per se and while the new
behavior is an improvement (IMHO) it's a (subtle) change in behavior which
might be surprising in the middle of a release series.

Maybe just backport the _POSIX_MONOTONIC_CLOCK part to fix(?) newlib targets,
and leave the windows stuff as is?
