I use freefall , FreeBSD 2.1.7 to recompile the client 8) Basically, we have taken yet another step back with gcc :( FreeBSD-1.0's gcc used to rock in terms of compilation it was at least twice as fast as the lastest gcc , and of course it didn't have any of the Pentium optimizations which may account for its current slowness -- well I am just giving it the benefit of the doubt. Someone ought to really look into what the hell is going on with gcc. Amancio >From The Desk Of "Jonathan M.
