floating point constant folding

[Hans van Eck]

Is it allowed to evaluate constant floating point expressions with greater
range and precision than that of the execution environment in contexts
where a constant is not required?

There are unexpected implications of both allowing and disallowing such
folding, but I cannot find a statement in the standard that unambiguously
says what a translator may or may not do.
