absolute value of min_integer a negative number?

[Dave Sworin]

I ran the following in gprolog 1.3.0.  (I typed this in by hand.)

--------------------------------------------------

| ?- current_prolog_flag(min_integer,MIN_INTEGER),X is abs(MIN_INTEGER).

 

MIN_INTEGER = -268435456

X = -268435456

 

yes

| ?-

--------------------------------------------------

Can someone check this on another computer?  I was working under Fedora Core 4,

using the kernel 2.6.11-1.1369_FC4smp on a Pentium 4 processor with

Hyper-Threading Technology.  I was pretty surprised to see the result of an absolute

value that is negative.
