A small floating point constant in gcc has type double. This can cause unwanted promotions
of other objects to doubles, like

float h()
{
	float f;
	...
	return f * 2.0;
}

as a trivial example. This has an "unnecessary" promotion of f to double, and a shortening to
float again on the return. It would be nice if sufficiently small/imprecise constants could
be of float type at least as an option, if not by default.

Not having an up-to-date ANSI C draft to hand I can't say whether this is allowed by the standard.
but it would be useful!
