HP-UX /etc/PATH

[Stuart Craig]

Attached is an improved patch for the HP-UX /etc/PATH file, which also
uses the compiled-in default PATH information.

So far, the new snapshot is working well under HP-UX 10.20, built with
gcc 2.95.  I plan to do more testing tomorrow, and I will also build it
using the HP ANSI C compiler, and test it under HP-UX 11 and Red Hat
6.2.
