This happen because you try to make quux has type of *function*,
not a function pointer. Sparse literary assign the base type of bar
as base type of quux. This result in body of bar get linearized twice.
I don't thing typeof(bar) quux is doing any thing useful.
I am not sure what is the gcc rules here. I try gcc -S with the test
case, it does not even generate any thing for quux.
The rest of the test case is more or less the same thing.

That is because, once you declear it as "extern", it does not emit
any code.
I guess I can skip typeof(function) to fix it, like gcc does. Is there
better suggestions?
