The C files are used to generate exectuable code which can be called 
from octave. The functions written in C usually can also be written as 
.m files, but some types of functions can run significantly faster when 
written in C. The makefile that comes with octave-forge should detect 
your system settings and build the C files--I think the README file that 
comes with octave-forge explains it.

It is possible to build octave-forge (and octave itself) and run in 
within your own home directory, but it's not the easiest way. If your 
system is Debian, precompiled packages are available and can be 
installed via apt-get. I have built RPM packages for Fedora Linux, but 
they are not very current. I'm working on updating it. I'll probably 
create a complete set of octave-forge and octave packages for Fedora 
Core 2 when it comes out in a few weeks.
