C++: __java_double expressions promote to float

Tue Apr 9 11:15:00 GMT 2002

TYPE_MAIN_VARIANT for __java_double is __java_double.
type_after_usual_arithmetic_conversions() doesn't know anything about
that type, so it converts to float. Therefore, expressions whose
operands are all of type __java_double are of type float. I think
that's wrong...

	* typeck.c (type_after_usual_arithmetic_conversions):
	__java_double expressions promote to __java_double, not float.
