gram.y has errors when processed by yacc (on Unixware 2.1.2) - Mailing list pgsql-hackers

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.
