  If a procedure is platform dependent then it should have the following tail:
    {$IFDEF IF_BASE_MEMBER}virtual;{$ENDIF}
  If a procedure isn't platform dependent, it is no part of InterfaseBase and
  should be surrounded by:
    {$IFNDEF IF_BASE_MEMBER}
      procedure MyProc;
    {$ENDIF}

  !! Keep this alphabetical and place a pointer to the independent part
  !! if needed
