It seems like there is only two possible patches here using the existing
infrastructure in acinclude.m4 that would allow darwin's nanosleep

The problem isn't finding nanosleep, it's finding what version of POSIX or
X/Open or SUS is supported, so we know

Yes, passing --enable-libstdcxx-time=yes and allowing nanosleep

I can confirm the existence of sched_yield() back to Libc-166 in 1997 on
darwin.

configure test is...
