Good point, I'll update that when we've sorted out whether we can
actually do this.

I think it should be the same (D = isDarwin, S = isStatic):

D=0, S=0 => orig = D == !S = false, new = D || S = false
D=0, S=1 => orig = D == !S = true, new = D || S = true
D=1, S=0 => orig = D == !S = true, new = D || S = true
D=1, S=1 => orig = D == !S = false, new = D || S = true (but that's
the whole point).

Thanks Renato.
