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.

This code was initially only tested on Windows, which doesn't use this padding.
 Linux also uses padding, though to 12 bytes instead of 16.  I've checked in a
fix that works on Linux.  It should work for Mac, too but I can't test it
because I don't own a Mac.  Please let me know whether it does.

Thanks for the fix.
I tested modified #0 code using trunk, No problem!
