Thanks much, looks like this should work. The patch is one line:
--------------------------------------------------------------
diff -c ompi_debuggers.c ompi_debuggers.c.old

#if defined(__WINDOWS__)

----------------------------------------------------------------
What would be the best way to put it in?

FWIW: there already is a flag in ORTE that gets set when procs are launched by
a non-orterun entity: orte_standalone_operation. So all you would have to do is
add an appropriate check for that flag to be true.
