Right, the answer is "no the --nfp switch is not used by binutils for
the PowerPC target (any CPU)". In fact looking at the GCC configure
files as well, it appears that this switch is not used there either.
The reason for the "--nfp is obsolete" comment being present in the
configure files is that it is added there automatically when then
configure file is generated from the configure.in file. The autoconf
program probably does not need to insert this comment any more (or the
lines that handle --nfp) but it is safest to leave them in case someone
has a very old configure command line lying around somewhere.
Cheers
Nick
