Date: Sun, 15 Sep 1996 17:19:02 -0500 From: Steve Price <sprice@hiwaay.net> To: hackers@freebsd.org Subject: patch to cleanup code generated by yacc(1) Message-ID: <323C80D6.1CFBAE39@hiwaay.net>

Hi all,
Attached is a patch that -Wall'izes the code generated by yacc(1).
Compiling yacc with -Wall still produces scads 'o warnings, but
at least the code that it generates is nearly -Wall proof. :)
