I am not sure on this but as I understand it the gcc that Apple ships
with their free developer tools has had some work done to improve
optimizations on PPC CPUs.

I haven't done Fortran, but C works fine using make and gcc from the
developers tool cd. As for problem areas I will mention that the way
they handle dynamic linking and building shared libraries is different
from the way I was used to on Linux, but it does work (after some
makefile changes).

One thing to keep in mind is that the new TiBooks have a DVI out rather
than a VGA out, meaning you will need an adapter to use many projectors.
