Okay, this is interesting. 0.95 seems to build fine on the ports
cluster, so bear with me for a second...

That's all that has changed from 0.95 to 0.96. Now, and this is the
tricky part, gcc 2.95 seems to be incredibly inefficient when compiling
the blit* bits (gcc 3.3 to a lesser extent too). The thing is, you can
actually compile this on RELENG_4... if you have 1GiB of total memory.
IIRC the cluster boxen have 1-2 GiBs, so that's why the problem went
unnoticed so far. How much memory does the box where you tried have?

So basically we have two options: Add a HEADS UP message informing
about the huge memory requirements (why hasn't anybody complained yet?)
or have this port build with gcc3.x, at least optionally. What do you
think? I'm not even sure the xmame guys support using gcc < 3.x

Cheers,
