But such ordering restrictions also apply to things like weak symbols,
so I don't think that imposing a link order restriction to solve
this issue is really a problem.

of the known order of static constructor invocation.  The splash screen
was executed from a static constructor in the first .o linked into the
executable.  I'm just curious if this is something the C++ spec says
anything about.  I'd be surprised if it didn't.
