Apology accepted. Again, however, it did cost me some time, which
a clearer error message would have saved me (and not because I am
unfamiliar with C++, but because I was working on someone else's
code). I hope that someone takes the patch I sent and considers
it for inclusion (or perhaps an improved version, since the one I
sent took about 5 minutes and was not based on an in-depth knowledge
of gcc).
