1. gram.y has errors when processed by yacc (on Unixware 2.1.2)

   Billy G. Allie <bill.allie@mug.org> — 1998-01-31T08:12:35Z

   The gram.y file in the snapshot file dated 30-JAN-98 causes errors when 
   processed with yacc on Unixware 2.1.2.  The following patch will enable yacc 
   to process the file, but I am unsure of the ramifications it will cause.
   
   Your comments please.

   I liked all of this patch, and have applied it.
