I recently came across a copy of stonybrook prolog and i've been trying to
get it running under HP-UX(6.01) on my HP9000s350. Before I go any firther
trying to get it running, I thought I'd ask the net a few questions:

1) I have version 2.2, are there any later versions, and if so, where may I
ftp it?

2) Has anybody gotten it running under HP-UX?? After SVIDing a few BSDisms
in the naming of some include files, I was able to get everything to compile
ok, but upon linking I get an error about the following missing function
> ld: Undefined external -
> 	_getrusage
Anybody have a clue or have a source for this function??

3) How does this version of prolog compare to other versions of prolog,
such as my old friend C-Prolog, or "University of New South Wales Prolog"??
I'm particularly interested in efficiency.

4) Any other good "public domain" versions of prolog out there?? I'm
looking for an efficient, C-Implemented prolog that comes with easily
modifiable source. sbprolog is the only one i've found so far that seems to
fit the bill.

A Zillion Thanks if you can answer *any* of the above questions.
