Organization is evil.
>Release: FreeBSD 2.2-960501-SNAP i386
>Environment:
I don't believe there have been any changes to the yacc code
since June 20, 1996, the date of the diff mentioned in bin/1337.
>Description:
This is a follow-up to bin/1337 since it seems I didn't quite
catch all of the warnings last time...
>How-To-Repeat:
Compile a yacc-generated parser with #define YYDEBUG.
>Fix:
