    Analyzed.

State-Changed-When: Thu May  1 14:04:33 2003
State-Changed-Why:
    As strange as it seems this is standard mandated behavior,
    corrrectly implemented by 3.2.x and recent releases.
    Indeed, according to 22.2.2.2.2,7 and 22.2.2.2.2,10 your
    testcase is equivalent to:
    #include <stdio.h>
    int main()
    {
      printf("%#x\n%#x\n", 0, 1);
      return 0;
    }
    Thanks for your report, Paolo.
