As far as I can see, all the types that are defined (in the original `int_types.h`) from line 124 onward, so after the `#endif // CRT_HAS_128BIT` block, are specifically meant for floating point support in some form or other. I wouldn't want to break any other uses though, there are a whole bunch of powerpc64 and 128-bit defines in between, and not all of them fall under `CRT_HAS_FLOATING_POINT`. I will just move only the really required stuff to the top.
