Google only turned up a patch from Mark Mitchell removing this in ~2001 timeframe. So again a pointer would be nice.
I use FC8: gcc --version gcc (GCC) 4.1.2 20070925 (Red Hat 4.1.2-33)
So this is far behind trunk that you use - but I have not had any real incentive to upgrade.
I would like to have a remote understanding of the options before enabling them.
