Doesn't this patch cause Linux to be more equal than other operating
systems, thereby causing free applications to be developed which won't
work anywhere else?

This solution does not seem to support the case where an actual
dependency exists but is not registered in the library (because the
user didn't supply it) so that the dynamic link loader doesn't know
about it?

If libone or libfour contain weak symbols, what happens?
