Does gcc support that? I won't worry if not though.

With a good compiler and good hackers, plain ARM will
fit just fine.

Alternately, one can easily switch modes by hand.

What extra registers? Why should gcc even care?

This does not matter. Linux itself is not a Linux program,
yet we compile it with a normal gcc just fine.

Both Debian-unstable and Fedora 8 appear to offer gcc for ARM.
I expect that both will work just fine.

Let's write from scratch. I think it will be easier.

By that you mean what?
