I do not believe we can safely set this on a global basis since that
might interfere with user code.

Rather, we would have to, where POSIX code uses uselocale(), retrieve
the current setting of _configthreadlocale, set it to thread-local or
save the current locale, set the correct locale, do our operation,
reset the locale, and then restore either the previous locale or the
global setting.
