This is not a matter of standards.  It's math.  Most of us have been
dealing with both integer and floating-point math in various forms long
enough to realize that it's possible to get these basics right.  I
wouldn't fall back on any standard to excuse the compiler.  I would,
however, blame the processor architecture or implementation, if it turns
out to be costly to implement.
