--- Comment #2 from mdblack98 at yahoo dot com ---
So how does one get this to compile then..Can't seem to find any combination of
parentheses that works.  I'm converting an entry in the hamlib project to an
array and that's what is causing this problem with static initialization of the
array.

  return 0;
