I too have tried to get this to compile on a 386 running ISC 2.0.2 SYSV
I get the same error when YACC tries to compile gram.c. I would be interested
in what the problem is.  I have also compiled it on the SYSV system here at
work and it compiles fine and runs fine.

Any YACC people out there that can help?
