  New Revision: 61826

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=61826

  Log:
    more ytab.sed fixes
    
    * tool/ytab.sed: `p` is too short to distinguish alone from other
      names.  fix for more old bison which does not support %lex-param
      at yydestruct.  add `p` argument to non-prototype declaration of
      yy_stack_print.
