Unexplained multiply defined _powf, _sinf, etc warnings



This may be a silly question, but I'll go ahead and swallow my pride...

When my project links for ppc, I always get a bunch of warnings that the
symbols _powf, _sinf, _cosf, _expf and a dozen of the other usual math procs
are multiply defined (when I have no such definitions).  Strangely, it
doesn't happen on every link, so it seems somehow tied to one or more files
getting recompiled, and it only seems to happen for the ppc link (not the
intel link).

Thanks,
Andy
