It sounds close.  But the problem is not so much as making gcc the
native compiler, but as making programs compiled with gcc native
programs.  A big fat warning about it is definitely in the right
direction.  

If you recompile and install a system binary (/bin/sh perhaps) with gcc
and then reboot you need a clue why it didn't work.
