At least for sparc and x86 which implement IEEE FP arithmetic, I don't
think this is right.  The CLHS says the normalized float must be a
normalized float.  If you make it the unnormalized one, then you're
wrong.  And the sparc and x86 have unnormalized numbers.

For the most part, it probably doesn't matter, but some numerical
algorithms expect them to be right.

I can help you get the right values, but I don't know how to tell gcl
to get the right values.
