I'm not aware of any yet, but I expect 3.1 to be the first widely used version of the 3.X series. There are several reasons for the delay: 1) 3.1 only released on May 15, 2002 2) 3.x series has a new binary ABI for C++ - the new objects don't work together with most binary C++ code compiled with 2.X 3) People like to use their system compiler for compiling the Linux kernel and there are always some things that don't work right away with each new compiler version, for various reasons. 4) Though nowhere near the Intel compiler on performance of numerical code, the 2.95.4 compiler is quite good and stable. The major distros will probably move to 3.1 by the Fall. It's not technically hard to compile your own version of the compiler from the source and install it under /usr/local or /opt as a non-system compiler. However, doing the build requires a bunch of other stuff (e.g. rpm packages if you use Redhat,Suse, etc.) to be installed first, which is described in the notes. -= Josh
