I have no explanation for this.

Negative BoundingBox coordinates are legal in PostScript, and reading
the code for the macro .PSPIC (see tmac.pspic) indicates that it should
handle negative coordinates without problems.

I then tried with the following code:

file BBtest.ps
==============
%!PS-Adobe-3.0
%%BoundingBox: -100 -100 100 100
newpath
-100 -100 moveto 200 0 rlineto 0 200 rlineto -200 0 rlineto 0 -200 rlineto
closepath fill
showpage


file testBB.tr
==============
.LP
.PSPIC BBtest.ps


and got the filled square where it should be (using ms macros).

Hmmm. (But then I'm not using Solaris ... ).
Ted.
