Note that gcc 2.96 is NOT an official gcc release by the gcc team. Redhat got
a development CVS gcc snapshot and released it as gcc 2.96 in their distribution.
The gcc team states that the object format used by 2.96 is not compatible with
neither 2.95 nor 3.x.

Eventually Redhat people got a clue and shipped a working compiler (kgcc).

I strongly recommend to use gcc 2.95.x or gcc 3.x for building the L4 tree.
Alternatively try compiling with kgcc instead of gcc.

This also works with gcc 2.95 and gcc 3.2. If you install a decent compiler
you'll save yourself a lot of headaches.
