In message <36628@netnews.upenn.edu>, George Jefferson asks:

> Does anyone know what change/improvement was made from 2.0 to 2.1.1

The major change between 2.0 and 2.1.1, aside from a fair number of
minor bug fixes, was the addition of support for the most important
elements of the Color P*stScr*pt Extensions, namely the CMYK color
operators and the colorimage operator.  There was also a very large
improvement in the speed of the X Windows driver.

The Ghostscript sources include a file history.doc that contains a
complete, detailed list of every change made in every release.
(Well, I do miss some now and then.)

And in message <1991Jan30.201620.9713@agate.berkeley.edu>, Geoffrey
Ghose reports:

> [making Ghostscript with Turbo C++ produces lots of undefined symbols
> because gdevs.tl is empty]

Sigh.  This is an old problem with the makefiles that many hours of
thought have produced no solution for.  The documentation (make.doc)
does say:

- Ghostscript version 2.0 requires that you build the device drivers
- individually, i.e., if your configuration includes device XXX, you must
- say
-	make XXX.dev
- before you say
-	make

I'd be surprised if this doesn't solve this problem.  Be sure to
delete gdevs.h and gdevs.tl *before* doing the above.  (I know the
doc doesn't tell you to do this.)

Geoffrey also asks about building Ghostscript on an IBM RT running
AIX.  I have a faint memory of someone else building Ghostscript on
an RT, but I can't retrieve the details.  If he can mail me the
compiler's output, I may be able to help diagnose the problem(s).
