// TODO: Is this still an issue? If so, investigate, and if not, remove this!
/*
* Unfortunately, GCC 4.8.2 stable still has a bug with their <float.h> that
* includes a different copy of <float.h> from a different directory.
*
* Until that bug is fixed, the below macro definitions can be forced.
*
* It also is possible to emulate the RSP divide op-codes using a hardware-
* accurate LUT instead of any floating-point functions, so that works, too.
