Ultrix 4.1 and TeX3.0/LaTeX2.09

[George Avrunin]

Richard Signell reported a problem with TeX on a DECstation 5000
running Ultrix 4.1 --- the compilation was ok, but LaTeX had problems
with math mode.  I had similar problems in November building TeX on a
DECstation 3100 under Ultrix 4.0.  Various pieces of text in math mode
simply disappeared.

I sent mail to the maintainers of web2c, and got a reply from Karl
Berry telling me that the version I had ftp'd from labrea.stanford.edu
(version 5.0c) was obsolete.  His suggestion was to "Get 5.8a from
ics.uci.edu [128.195.1.1], in the directory TeX."  Apparently the
problem is due to a missing cast somewhere.

I haven't done this --- I had already succeeded in building a working
TeX on a machine running Ultrix 3.1 (with optimization), but Pierre
MacKay sent me a message saying that he had built a working version
with optimization on a beta-test version of 4.1.  So the later release
of the web2c stuff may solve Signell's problem as well.
