Sigh. Ok, here's a modified install script I used. I needed to modify it,
because I installed gcc from a DOS partition, where the filename conflict
was a real problem. Just copy all the gcc .tar.Z files into a single directory
along with this install script (use any names you like), configure the file
names at the start of the script and run it. If you still can't get it to work,
please don't flame me. HLU's script was ok, and so is this one. If you get a
mangled file system, your problem is probably somewhere else. Any one of the
utilities used in the script could be broken.
