Right, on 32bit it's largely a non-issue. But on 64bit platforms, we need a floating point type that's bigger than the integer type, as stuff inside the interpreter and runtime library make this assumption, and though it's possible to rewrite the insides to avoid this, it'd probably mean a lot of Euphoria code would also need to be rewritten.
The real portability/compatibility problem comes from 32 vs 64 bit integers, instead of defining Euphoria integers as definitely one or the other.
THAT's where the biggest incompatibility will be. If we say that Euphoria integers are AT LEAST 64 bits (a performance issue only on 32-bit machines) then we should be okay. But if we say that integers are 32 or 53 bits on 32 bit machines, but 63 bits or 64 bits on a 64 bit machine, then we may have problems.
