New Revision: 528172
URL: https://svnweb.freebsd.org/changeset/ports/528172

Log:
  Create a bison wrapper on top of base byacc
  
  The wrapper deals with various simple incompatibilities between byacc and bison:
  * first deals with --version which might often be called
  * --verbose and -v are ignored
  * normally yacc is called like this: yacc [options] input, but with GNU programs like bison
  the input can be mixed in the middle of the arguments, unmangle that
  
  Add a new 'wrapper' argument to USES=bison use the wrapper
