Well, it worked until I started "depending on it".  Then it stopped.
So I guess that, at least for exceptions, they need to be defined within 
the same file that they are used for rdmd to be happy with them, though 
clearly that's not true for the standard libraries.  And I don't know 
where the boundaries are.

This is particularly weird, because when I try to create a simple 
example case it doesn't display the problem.  Not too surprisingly it 
depends on the presence of the unittest parameter, though even that's a 
little surprising as I haven't yet added any unit tests.  Still, without 
the unittest it isn't even thinking of executing anything.

Still, for some reason if the exception is defined in a separate file 
(utils.d) it can't find the symbol.  I even tried including utils.o 
instead of utils.d.  No change.

FWIW, I invoke the exception with:
default:
	assert	(false, "internal logic error");
	throw	new	LogicError ();
in a few places.  As I said, I haven't written the unittests yet, so 
even the assert has never been called.  Still, that's a consideration 
that happens much after linking.
