[David E. O'Brien]

Author: obrien

New Revision: 258931
URL: http://svnweb.freebsd.org/changeset/base/258931

Log:
  Add missing bits from the vendor's 2005-05-04 change to
  contrib/byacc/makefile.in ("add YYPATCH here so it can be tested by
  applications") so that applications have a hope of detecting newer
  FreeBSD YACC output from an older one.
