Now thinking about it, need_line being true before the call to
_cpp_handle_directive is causing PR 79516. Though there in_deferred_pragma
should be false at the point of #if anyways. So that is the right fix there
still. Here we definitely need to set it to false before calling
_cpp_handle_directive .
