In my previous article, I forgot to mention that the getuser() routine also
fails due to some un-initialized pointers. It apparenly checks the
environment for some variables, and if not found tries to do a strcpy()
into a null pointer. I beleive the variable is USERNAME or some such. I
can't remember off hand ( there was a lot of code ).

Basically, make the previously mentioned fixes to pathinit.c, then compile
the program being tested. Here are the definitions used in the Makefile. I
have found these to work very well.

Hope this information helps,
