I'm sure there are bugs in gcc 2.96-81. The same kernel compiled for k6 made
filecorruptions and complied for i586 it worked. I think even in 2.91.66 are
(unknown) bugs. Compiler are very complex.
I dont use a experimental state filesytem (or kernel) with an experimental
state compiler.
I also think redhat ist right using gcc 2.96. I had too many bad experience
with 2.95.2. But compiler for kernels are a different thing.
