Revision 1.5 1991/03/01 17:28:00 sm
ANSI prototypes inside ifdef __STDC__ s since y.tab.c to complicated for
ANSI filter
Revision 1.4 1991/03/01 16:32:28 is
Modified read with line numbers I guess.
(kjp)
Revision 1.3 1991/02/13 19:53:58 kjp
New error handling on parse errors.
Revision 1.2 1991/02/11 18:01:44 is
