    No. The story is like this....

    I upgrade my gcc to 3.3.1 on my host and start to compile my cross
toolchain. However, while it is compiling gcc, it has strange error that I
have never seen (seems gcc has made something that ld can't understand). So,
I guess gcc 3.3.1 may not work very well with my old glibc (provided in
RedHat 7.2). I don't know how to upgrade glibc safely and make it compatible
to existing applications. That's why I would like to upgrade the whole
Redhat.....and this is painful...

        I use CVS to grab the linuxppc-2.4-devel module. Is it the same as
that? Thanks.
