Ahmmm ... AFAIK the eps2write is the replacment of epswrite that is it should work out of the box without changing anything. Or in other words: esp2write outpout should be compatible with the old epswrite output. What is the reason for ghostscript upstream to break existing programs. Do you know what Linus Torvalds does in such cases? AFAIK Linus does not accept any change in the kernel which break user space programs. I'd like to see the same behaviour in the ghostscript PostScript kernel world.
