Introduce vNULL to use as a nil initializer for vec<>.
This patch implements Jakub's idea of adding an empty struct with a typecast operator that returns nil vectors. This is useful to shorten all the initializers when declaring vec instances or passing nil vectors as function arguments. 2012-11-20 Diego Novillo <dnovillo@google.com> Jakub Jelinek <jakub@redhat.com> ChangeLog * vec.h (struct vnull): Declare.
