--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Making this work requires splitting <mutex> into smaller pieces so that
std::timed_mutex can depend on std::condition_variable, which depends on
std::mutex.
I'll come back to it.

fix for bootstrap fail
thanks for working on this Jonathan,
small glitch: as of 227490, bootstrap is broken with problems in
libstdc++-v3/include/std/mutex.
the patch attached allows bootstrap to complete - but I can't be sure it's what
you'd intended.

I wasn't actually testing the new code at all due to a cock up when trying to
undefine the macro that differs between darwin and other targets. Should be OK
now.
