But the patch certainly brings another things:
a) __convert_from_v must not use setlocale but uselocale for GLIBC 2.3+.
b) is "C" locale really the right one to use, or should it use the
   const __c_locale& argument?

a) is further complicated by lack of __uselocale prototype, so I'm afraid
   we might need the:
   namespace __gnu_cxx_loc {
     extern "C" __typeof(uselocale) __uselocale;
   }
   ...
   and use __gnu_cxx_loc::__uselocale()
