I've been running a * (cvs HEAD) instance on Debian unstable, which has
upgraded to gcc 4. Gcc 4 still has problems compiling the kernel (as of
2.6.12) on debian, and you want to use the same version of the compiler
on the zaptel modules that you do on the kernel. 

I was unable to get a clean compile of the kernel or * with gcc 4.

The good part is that I have gcc 3.3 on the system too, so it's an easy
symlink change. It may be that gcc 3.x is available on suse either by
default or an additional package.

Considering how new gcc 4 is, and how many major changes there were with
it, I personally would wait another 6 months to a year before using it
in production.  I've also read stories that gcc 4 produces slower code
than gcc 3.

I'm sure others will have some insight as well :-)
