What standard or version should I check for to detect nl_langinfo_l
support? It's in POSIX 2017 but macOS supports it in <xlocale.h>
despite not being POSIX 2017 compliant.
What about _get_osfhandle? Or fwrite_unlocked?
What about whether the platform ABI allows aligning global objects to
the cacheline size?
Those are just a few of the most recent autoconf checks I've written
for libstdc++ in the past few months, not decades ago.
