float.h again

[Ulrich Drepper]

I've sent a patch like this quite some time back and got only one
reply pointing out a duplication.  Here it is again, with the problem
removed.  I'm using this patch in my tree (and the system itself) for
weeks without problems.

Can I check it in?  The comments added should be sufficient for others
to fill in the details for other architectures.
