Yes, actually the standard just says that "the type double provides at
least as much precision as float, and the type long double provides at
least as much precision as double." ;-)

BTW, I am surprised MSVC++ doesn't provide its own long double type
(80-bit long). Really nothing like __float80, __quadruple ?

I think that an implementation claiming IEEE-754 compliance would have
adequate float and double type representations. long doubles could also
be 128-bit long.

I wonder if some checks could be done at ./configure time...
An alternative is still the implementation with hand-coded float types
as with the FPE from NetBSD/m68k. That's a lot of work. I would prefer
working on a faster m68k core or a PPC core ;-)))
