Until now this has not been an issue - for the sparc bits.

If newer gcc's turn out to give legit warnings then if someone provides
a little help (configure command-line to build gcc) the warnings will
be fixed. And that should hold true for any decent maintained piece of SW.

If the intent is to use bleeding edge gcc then -Werrror can be annoying
and the right fix would be to make it possible to diable it on the
command-line.
