--- Comment #5 from Kai Tietz <ktietz at gcc dot gnu.org> ---
This patch is clear stage 1 material. Patch itself looks ok, but raises a
completely different question.  Modern versions of mingw provides all
Interlocked-functions, so we might want to use this instead.  The argument
about Win95/98 compatibility is actually pretty borged, as we have already in
some of gcc's target-libraries strong requirements of using at least NT 4.0,
and/or even more modern.
