Trouble compiling TeX on SCO XENIX

[Kevin Dooley]

I am trying to get a full implementation of TeX running on an
SCO XENIX 2.3 386 machine.  I fixed the few obvious problems
of file name length limits and the few include file differences
which the compiler choked on, but I still get this sort of error.
Can anybody offer any assistance?
