Within a #import directive, this attribute expects no arguments. It is just function_mapping.
The function_mapping attribute is cancelled by demand_load, but not exactly as if function_mapping had never been given (and not as if no_function_mapping had been given). More investigation is required.
The function_mapping attribute is incompatible with no_function_mapping. To give both is equivalent to giving neither, except for a warning (C4187).
