/* NOTE: drow/2003-09-06:
This function is "a step sideways" for uses of deprecated_selected_frame.
They should be fixed as above, but meanwhile, we needed a solution for
cases where functions are called with a NULL frame meaning either "the
program is not running" or "use the selected frame". Lazy building of
deprecated_selected_frame confuses the situation, because now
deprecated_selected_frame can be NULL even when the inferior is running.
This function calls get_selected_frame if the inferior should have a
frame, or returns NULL otherwise. */
