I see REDHAT supports FEDORA and then uses their OS later on but doesn't
want to be associated with FEDORA when things go wrong? You cannot have
your cake and eat it at the same time? So which is it?

I was wondering out loud - Aren't all libraries backward compatible?
Would the lastest gcc and it's libraries be backward compatible to
gcc2.96? and if not, can your system have gcc 3.4.1 environment at the
same time as e.g. gcc 2.96 environment. So the real question is ---
How can I configure these various environments and switch between them?
That's where I'm coming from?
A side note: Didn't ORACLE8i need certain libraries ONLY from gcc2.96
environment for it to function properly? Isn't it also the reason that
RedHat wanted to stay with a compiler for a certain amount of time
before releasing the next version? Or what was the real reason for
staying put?
