Hi!
RedHat team should answer this question, I know, but this is my personal
experience:
I used to set a variable:
export CC=egcs
in some file on the /etc/profile.d/ directory.
That worked in the case you can configure by yourself the program, but not
when you must use an already configured pkg.
To have the things right forever, I decided to install the gcc-2.95, but
leving the gcc-2.96 in place (it can be useful).
Step one was to download the gcc and the patch for glibc 2.2 (2.9x on RedHat
Linux 7.0) from the gcc home page.
After all, start the compilation of the gcc (install dir = /usr/gcc-2.95).
Just remember to give this line to the configure:
--prefix=/usr/gcc-2.95 --enable-threads --enable-version-specific-runtime-libs
This will set the path in the /usr/gcc-2.95 dir but, above all, will
preserve all the old gcc library, installing the new library in a gcc-2.95
path.
Compilation will take less than an hour (I think, as my machine is very slow,
and it takes one hour exactly!).
Before to run make install, remember to save all the compilers (see the list
by using rpm -ql gcc, rpm -q gcc-c++ etc..) of the gcc-2.96 pkgs, with the
name gcc-2.96, g++-2.96 etc...
The only step needed now is to make a simbolic link from /usr/gcc-95/bin/* to
/usr/bin (or adding the /usr/gcc-2.95/bin directory to your path).
I hope that will help!
Bye
Mario
