Re: [PATCH, v3] Bringing <mutex> and <condition_variable> up to spec.
Hi,
and, first, many thanks.

I think the first changes that we have to sort out are those affecting gthr: these changes are delicate, because impact also users of GCC not using libstdc++, not even using C++. In particular, I'm afraid the current set of changes would essentially broke any target not using gthr-posix (or gthr-single), because __gthread_t would remain undefined, still used in gthr.h.
In any case, recently we ("libstdc++ people") never touched gthr and I think we need some guidance about this type of changes from the core compiler maintainers. I'm hoping Ian can help us about the best way forward...
Paolo.
