I'm using the gcc port from codito.com; it is based on gcc 3.4.5 and
binutils 2.15. I've added an arc-rtems target to it, based on their

I don't have a simulator (at least not that I know of - I do have some
Metaware tools, but I haven't noticed a simulator as part of them). I
know I don't have a gcc target and simulator setup to work together.

Yep, that's the sequence I'm planning to do, except running on some real
hardware instead of a simulator.

The next goal after getting rtems running is to run nanox. I know nanox
has some rtems support in it; do you happen to know if that support would
be any further from working with the CVS head vs 4.6.6?
