OK, I do see now (that you arranged to properly reuse the
implementation from elsewhere that has the same bug I was attempting
to fix).  FYI, trivial bootstrap issue with mainline g++:

c++locale.cc: In function `void std::__convert_to_v(const char*, _T&, 
   std::_Ios_Iostate&, int* const&, int) [with _T = long double]':
c++locale.cc:171: using `typename' outside of template

[where c++locale.c == config/locale/c_locale_generic.cc]

BTW, yes I do have:

        * config/locale/c_locale_generic.cc: Fix.

in my tree already.

I think you must be using an older g++ that allowed typename to appear
in this context.  Since mainline bootstrap is broken on non-C99 ports
and I'm fairly sure I remember this being recently tightened in g++,
applied as obvious:

        * config/locale/c_locale_generic.cc: Fix typename usage.
