I tested following code using dmd 2.047 on Mac OS X 10.6.3.

-----
import std.numeric;

void main()
{
    CustomFloat!16 a;
}
-----

compilation result:

std/numeric.d(476): Error: template instance ToBinary!(real) does not match
template declaration ToBinary(F) if (is(CustomFloat!(F.sizeof * 8)))
std/numeric.d(476): Error: ToBinary!(real) is used as a type
std/numeric.d(476): Error: variable
std.numeric.CustomFloat!(precision,exponentWidth,flags,15).CustomFloat.get!(real).get.result
voids have no value

I think this cause is real type size. real.sizeof is 16 on Mac OS X, but
current std.numeric.CustomFloat can't treat those environments.
