(Catching up with this thread...)

LC_C_LOCALE is definitely not portable: I've only seen it on macOS and
NetBSD. It would be a good thing to propose to POSIX, since no other
approach can be retrofitted quite so cromulently...

I tried to make a portable PG_C_LOCALE mechanism like that, but it was
reverted for reasons needing more investigation... see
8e993bff5326b00ced137c837fce7cd1e0ecae14 (reverted by
3c8e463b0d885e0d976f6a13a1fb78187b25c86f).
