I see that the setlocale code is a bit meatier than I would have expected.
On the other hand, a few string comparisons followed by setlocale is
potentially even worse for those using other than C/POSIX.

GNU libc seems to have an "extended locale model" allowing strtod to
take a locale argument; however, this is neither portable nor standardized.

I'm also beginning to wonder if prev_locale won't get clobbered somehow.

On sheer byte count or by some other criterion?
