Maybe I'll have to go back to the old setup, then ;-(
This is a bit depressing... I've been using a compiler from Microware
released some 20 years ago, and generates binaries that are about half
the size of the gcc ones, and even without optimisation are faster than
gcc -02 output... It's only running on a (different) Motorola board,
though, which is why I'd prefer using a gcc cross compiler setup

OK. I also want to generate rpms (do you support that?), so I've written
my own a spec file, but it has borrowed a lot from Bill Gatliff's
Actually, gcc 3.3.3 did work all right, but I'm not actually able to
generate the application with it (yet.)
