Presumably we have a tool - automoc ? - that scans our source to
determine which headers need to be moc'd and which resulting moc output
isn't already #include-ed, so needs separate compilation. We can surely
adapt that tool to (when a suitable option is passed) produce a warning
when such separate compilation is needed, advising us to do the #include
instead.
