Okay. Thanks everyone. I found it. Aparently something was "down"
this morning when I was trying to get the sources off from gnu.
I just downloaded gcc-2.3

However, it has the same problem. It won't compile with the egcs-2.91.66
version installed here.

This comes from using strchr(s, 0), to find the end of a string! I can't
find anything about '__rawmemchr()' so I don't know how to make one.
