  16 dnl Additional SIM options that can (optionally) be configured
  17 dnl For optional simulator options, a macro SIM_AC_OPTION_* is defined.
  18 dnl Simulators that wish to use the relevant option specify the macro
  19 dnl in the simulator specific configure.ac file between the SIM_AC_COMMON
  20 dnl and SIM_AC_OUTPUT lines.
  21 dnl
  22 dnl Specify the running environment.
  23 dnl If the simulator invokes this in its configure.ac then without this option
  24 dnl the default is the user environment and all are runtime selectable.
  25 dnl If the simulator doesn't invoke this, only the user environment is
  26 dnl supported.
  27 dnl ??? Until there is demonstrable value in doing something more complicated,
