[Additional note: Another site reports that version 2.1 of the High C
compiler dumps core, but that version 1.4 works fine. ---Tim]

First I would like to thank all of the people who took the time to
respond to my plea for help.  After mulling over all of the
suggestions and comments I went back and reread the tex82/README.  In
there are mentioned some hints about unsigned char types and others
useful info.  All that I ended up needing to do was to add a few
`pragma' statements to tell MetaWare High-C to behave a bit more like
the portable C compiler.  Attached is a context diff for site.h that
actually got TeX to compile.  It even passes TripTeX now.  One other
point I failed to mention in my original message was that BIGTEX.PATCH
had been applied to ctex.ch and that `glueratio' was changed from a
float to a double in site.h.  An oversight on my part.

The next problem is to try and figure out why undump doesn't work
properly on the RT.  Undump on the RT is setting the data segment
length to zero so it's not saving any of the preloaded format
information.  Anyone have any thoughts on this one?

Thanks again for all the help.
