No I didn't modify GCC or libstdc++ source. The "" (empty string) locale
works fine and conforms to the standard on my computer (that is, it is
identical to the "C" locale).
So where did you get the code? Libstdc++ in current GCC trunk throw
exception for all locales (even if "") except "C".
I'll look at the standard. Maybe upstream libstdc++ need a fix for
"" locale.
