Section 6.9.3.3 does in fact impose many constraints on the sequence in
which non-local objects with static storage duration get initialized.
However, all of the sequence requirements are only between objects
defined in the same translation unit. Also, it's implementation-defined
which of those initializations occur before the start of main().
