Yes, that is probably a better way to do it. I followed numarray's lead
in how they were handling the IEEE floating-point stuff
platform-to-platform. But, we could take advantage of the decent
configuration system already present where we detect quite a few things
at build time in the setup.py file. Tests for the existence of
different IEEE functions could be defined there as well.
The presence of specific functions would tell us which method is being
used and we could then define a UFUNC_IEEE_FPMETHOD variable that
specified which type was in use.
The only other problem is that different platforms need different header
files for this capability, so we would probably need to define another
variable to pick-up the correct headers which would complicate matters.
