I'm not aware of any GCC interoperability problems besides the
conflict that often occurs with objc_malloc conflicts with versions
of same in tclobjc.  That's not really a GCC conflict, but a change
in the Objective C support library that occured with version 2.8.
As far as I know GCC 2.8 and EGCS > 1.0 are compatible for this application.

It's possible.  The only way to know for sure is to try.  On a
GNU/Linux box there are all sorts of potential problems with
libc5/glibc2/libstdc++/gcc interoperability (that are slowly but
surely getting sorted out).

I don't know how Redhat is set up, but there is nothing about GCC that
prevents you from having gcc 2.7.2.3, gcc 2.8.1, egcs-1.0.3, and egcs-1.1
all on the same system.
