I'm still working on this, it's just not very high on my list (since
the devel one works, and we could use compat for the old one).

The compat compilers/libraries are used by specifying CC=egcs and
CXX=egcs++

When I last tried to build octave 2.0 with the new compilers, the
problems were illegal use of keywords as enums and macro magic. Since
then (this was quite some time before the release), the compilers got
pickier so it now dislikes the way readline functions is used as well
(and I still intend to look into it...).
