    usr.sbin/config      config.y 
  Log:
  Spring forward into the late 1970's by following item 5 in the yacc
  manual's Appendix D ("Old Features Supported but not Encouraged") in
  the Seventh Edition Unix Programmer's Manual (January, 1979) by
  retiring the " = {" method of of action specification in favor of a
  plain "{".  It is no longer necessary for this bootstrap program to
  be compatible with 6th Edition systems.  Some yaccs in the wild do not
  support this old syntax any more, and compatibility with those systems
  is more important these days (as there are easily 7 orders of magnitude
  more of them than real v6 systems today).
  
  Reviewed by: jhb@ and dds@ (the latter gave the reference).
