Hi! Sure: the coming (and optional) gcc plugin "randstruct" performs
structure layout randomization, which means that static initializers
cannot be "ordered" (they must be "designated"), since the place were
layout randomization occurs happens separate from how static
initializers are applied.

This change from ordered to designated is just to help the compiler do
the right thing.
