Good choice of reading :) I have been looking at the RISC OS port again
recently after a fairly long break being distracted with other things.

I did build kaffe from cvs about 2 weeks ago using the current RISC OS
gcc cvs (3.3.3), but up until a few minutes ago I didn't think it was
working. It does seem to be working now though :)

I know what the difference is in the way I'm running it now to then, so
I just need to work out why it makes a difference.

(For Peter's benefit: It works when it's using dynamic areas, and fails
when it isn't.)

So, there is some progress in that I have a version that seems to be
working on the same things as the last released RISC OS port, but still
failing on the same things too. Hopefully I'll have more time to look
into the issues now.

BTW, the change to COMPARE_AND_EXCHANGE doesn't actually work with the
RISC OS assembler, but that's easy enough to sort out.
