--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
An initializer for an union is a single value.  In C89, only the first member
of a union can be initialized; in C99/C11 you can use the designated
initializers to specify which member to initialize, but still only a single
member of an union can be initialized.
