Yes I think so. Acrobat Distiller seems to be able to do the right
thing. I've also seen similar bugs in output from various other
programs.

In your example, I modified the coordinates to give a slight overlap
(making each rectangle 100.1 points wide) Whether it would be practical
to do this in the postscript terminal is another matter. (I guess you'd
have to find the centroid of each polygon, and then scale all the
coordinates.

Maybe there are other approaches, but I suggest leaving it - people can
either a) live with it b) turn of antialiasing or c) wait until
ghostscript fix the bug.

You might want to post a bug on bugs.gnuplot.com
