... but isn't __add_signed necessary anyway, from out point of view? Imean, we would have,

template<typename _Value>
  struct __add_signed

template<>
  struct __add_signed<char>
  { typedef signed char __type; };

...

template<typename _Value>
  struct __remove_signed
  { typedef _Value __type; };

template<>
  struct __remove_signed<signed char>
  { typedef char __type; };

...

Ah, yes, as far as __add_signed and __remove_signed are concerned, the ellipsis can be removed, no additional specializations are needed, AFAICS (well, at some point we'll get compiler support for the traits, then no specializations at all ;)
