The trouble is, which version? The Linux kernel itself is not stable. To make a useful benchmark, you need to pick a specific version of the Linux kernel. Old versions of the Linux kernel don't work with current versions of GCC, and probably current versions of the Linux kernel won't work with future versions of GCC. -- Fergus Henderson | "I have always known that the pursuit The University of Melbourne | of excellence is a lethal habit" WWW: | -- the last words of T.
