HEADS UP: gcc update work in progress

[matthew green <mrg%eterna.com.au@localhost>]

hi folks.


as many of you are aware if you follow source-changes, i've started
updating our gcc to 4.5.3.  it will probably be a while until it's
ready for anyone to test/use, but in the mean time it is possible
that i/others will break the tree while preparing this support.

as always, please send-pr any problems you may see, and i will let
everyone know when it's time for testing.
