Please consider the following program schema and questions.

// Declare class A with non-trivial constructor
#include "a.h"

static A a;

int main()
{
   // Nontrivial use of a
   return 0;
}

(1) Will the standard require that a's constructor be called?

(2) If the answer to (1) is "yes", will the standard impose any constraints
    as to the time at or by which the call must occur?

(3) If the answer to (1) is "yes" and the answer to (2) is "no", does not
    this imply that a compiler is free to time the call to occur whenever
    it likes, say, immediately prior to termination of the program?

(4) If the answer to (1) is "yes" and the answer to (2) is "yes", what are
    those constraints?  Please answer in the most general form.

Thank you.
