<<Does GNAT support the IEEE representations of infinities and
Not-A-Number (nan) specified in "IEEE Standard for Binary Floating-Point
Arithmetic ANSI/IEEE Std 754-1985" or "IEEE Standard for
Radix-Independent Floating-Point Arithmetic ANSI/IEEE Std 854-1987"?
>>

This is a potentially target dependent question, but in general, yes,
in most GNAT implementations, Machine_Overflows is false, and we generate
appropriate code to generate and handle infinities and NaN's.
