Yes, C99 guarantees in 6.7.8 p19:

The initialization shall occur in initializer list order, each
initializer provided for a particular subobject overriding any
previously listed initializer for the same subobject; all subobjects
that are not initialized explicitly shall be initialized implicitly the
same as objects that have static storage duration.
