Perhaps.  I supported it only because the original bug report lists
"-nfp" as one of the options used, and that just says "obsolete, use
--without-fp" so I supported that.

I would be more willing to remove that in the patch, and simplify it
to just use --with-cpu, but then there's no way to get bugwards
compatibility.
