2.8.0 has some known problems. 2.8.1 is better, don't know how much
better tho.

If you have the space, it's nice to have several available on your
system, so you can build your system-critical stuff (kernels, libs,
etc) with the "more stable" 2.7.2.3, but build less critical things
using the alternate compiler. For example, I have 2.7.2.3 and EGCS
installed on a cluster of RH 4.2 machines here... "gcc" usually
resolves to /usr/bin/gcc which is 2.7.2.3, but I can pass
"CC=/l/local-libc5/egcs/gcc" to Make for builds using EGCS, like for
my high-performance experimental threaded web server code ;-)
