two quick questions:

1. does a version of C-Prolog exist for the Mac ?
(or can the sources for Sun be easily ported and re-compiled ?)

2. has anyone access to numbers comparing the relative efficiencies
of different Prologs on Sun-3 and Sun-4 ?
what i'd really like are stats for database manipulations 
such as assert/1, retract/1, bagof/3, setof/3, retractall/1, etc.

here at laas there are 3 Prologs floating around: C-Prolog, Quintus
(for Sun-3 under OS 3.5) and BIM (also for Sun-3 under OS 3.5)
and i'm trying to compare them in various ways.
(yes, i'm aware that comparing interpreted and compiled Prologs
isn't fair, but to paraphrase Groucho Marx, that's not important here*)

thanks
paul
