  * src/vm/cmdarg.c
    % do not process CLIPPER envvar unless HB_CLP_STRICT is enabled
      (The only documented option that overlaps between Clipper and
      Harbour is //info, so while INCOMPATIBLE, in practice it's unlikely
      to cause any problem - the only undocumented one is //NOALERT)
      If you use Harbour exclusively, change CLIPPER envvar to HARBOUR
      to specify runtime envvar options.

  * src/vm/harbinit.prg
    % do not include compatibility symbols CLIPPER520/CLIPPER530
      unless HB_CLP_STRICT is enabled
      (INCOMPATIBLE, if your code happens to rely on these symbols)
