gcc 2.96 has never been released. Look at ggc's home page. gcc 2.96
is only an unofficial name given by RedHat to a gcc snapshot they used
for their beta release. They used this version because they wanted to
use a newer still beta glibc who cannot be compiled either by egcs or
by the official gcc ie gcc 2.95.2

You can compile kernel 2.2.16 with gcc 2.95.2, however it should not
be used with older kernels due to kernel bugs revealed by gcc's better
optimizer. The low risk aproach however is coimpile kernel with egcs:
it has been around for far longer and in addition use of gcc 2.95.2 gives
little for kernel compiling: it only generates marginally faster
integer code, it generates significantly faster floating point code
but in the kernel you don't have a single floating point instruction.
