This is a damned-if-we-do / damned-if-we-don't situation.  The problem
is that the Linux yacc is actually just bison in disguise, and bison
doesn't seem to produce a viable gram.c.  While it is possible for
Linux users to run off and install byacc and use that, it is a hard
solution for many.  (We left gram.c in this time specifically to help

Probably the right solution is for me to find an ``ansi yacc'' to
install on our development system and produce a gram.c with that.
I'll check it out.
