I have not yet had a chance to test these patches. But is it really the
correct approach to set the locale to "C" whenever a number literal is read or
written and to set it back afterward? (Btw., is setlocale() thread-safe?)
Wouldn't it be simpler and more reliable to have number conversion functions
that are independent of the current locale?

Maybe I'm missing something, but declaring a variable volatile does not
automatically make it thread-safe, does it?
