Thanks, but I'm not sure that it's Magma causing the problem: I did a
search through references to ProtoObject, and found that
TraitsResource (in Traits-Tests) looks like the guilty party - it has
three methods setUpTrivialRequiresFixture,
setUpTwoLevelRequiresFixture, setUpTranslatingRequiresFixture - these
include lines like (for C3, C4, C6):

	self c3: (self
				createClassNamed: #C3
				superclass: ProtoObject
				uses: { }).
	self c3 superclass: nil.

Sooo, it doesn't look as though getting rid of these classes will
break anything, but I can't see why they're still hanging around!

Can anybody help me take this any further or should I be looking to
the general list?

Thanks,
Michael
