Here is the situation with compilers for redhat 7.1: 1) the default redhat-7.1 compiler is gcc-2.96-RH. It is supported by ROOT and appears to work okey. (Christian's claims to the contrary not withstanding). 2) egcs-1.1.2 (redhat-6.2 compiler) is installed (by default?) and can be accessed by using "gcc -V egcs-2.91.66". I did not test it extensively, but it should work the same as on redhat-6.2. (the "compat-egcs-*" rpms). 3) gcc-3.0.1. There now are gcc3 rpms in redhat-rawhide (redhat beta). I did not test them yet, but presumably they work. (the "gcc3-*" rpms). All of these compilers can be installed and used at the same time. To summarize- with redhat-7.1, the old compilers are still available, plus there are two new ones (so use the compiler that works the best). I would suggest this- get one redhat-7.1 machine, compile, run and test your software, and if everything works, upgrade. But do keep one redhat 6.2 machine around, just in case. K.O.
