It would be interesting to hear why, since that's the only official way
to get at variadic arguments.

Variadic arguments always have the default argument promotions applied,
so yes, a float argument appears as a double to va_arg().

The only official way to build a variadic argument list is to invoke
a function whose type was declared using the ,...) notation.

If you devise some other kludge, it is subject to breakage without
notice in future compiler releases, or when porting to another
implementation.
