The above isn't exactly true.  No one has stepped forward to integrate
newer versions of gcc into the base system.  If you decided to do the 
work, I suspect the FreeBSD committers would be interested in your
work.  You simply need to introduce "make -DWITHOUT_GPLV3" into
Makefile.inc1 and isolated the problematic licensed code.

I've already stated that the FreeBSD documentation clearly states
that only -O and -O2 are supported optimizations.  Any other 
choice is unsupported (see make.conf(5)).

Doctor:  "Well, don't do that."
