Function pointers. There's an issue where 'alias f = extern(C) void function()'
does not work (it's a filed bug). Until that is fixed we can't plan to go
forward with this warning.

I would also argue that we should start developing a D porting tool that
auto-converts the old alias syntax to the new one. It should be trivial to
implement and should get rid of the nuisance of manually fixing code.
