Sanity check: Build with gcc3 known to fail?

[Nigel Head]

Having just tried to build r9b1 on a SuSe8.2 system (which has gcc3) and got reams and reams of compare signed/unsigned warnings -- which look benign -- and some token pasteing errors -- which look less benign -- and a failed install I thought I'd check if this is known to be a problem by any of you old hands. I don't easily have an older gcc available to go the 'trial and error' route and I'm new enough to erlang to have only used the windows binary distribution for toy things so far, so I have no basis for comparison.

TIA;
Nigel.
