Comment (by howarth@…):

 Also note that passing --enable-libstdccxx-time=yes  causes
 libstdc++-v3/configure  to check...[[BR]]
 [[BR]]
 configure:19382: checking for clock_gettime, nanosleep and
 sched_yield[[BR]]
 [[BR]]
 and darwin doesn't provide  clock_gettime. It is unclear how important
 that is to the enable-libstdccxx-time option[[BR]]
 functioning.
