Red Hat 7.0's "GCC 2.96" is binary compatible for C with all past and

It is the *kernel's* fault, as far as can be ascertained now.

It has come to our attention that some GNU/Linux distributions are

We would like to point out that GCC 2.96 is not a formal GCC release nor
will there ever be such a release.

Hi,
You can blame it on the compiler which is included with RH7.0. It's a
pre-release version of
some sort. It seems that the gcc people are not happy that RH included this
version with RH7.

RedHat includes two versions of gcc. gcc-2.96 is a developmental snapshot
of the compiler project and is not able to build a kernel. Also included
is kgcc, as in KernelGCC, which is what you should be using. If you don't
have the kgcc...rpm installed, install that and use it.
