try

bool test;
windowProc()
{
         switch (cmd & 0xFFF0)
         {
             case SC_MAXIMIZE:
             case SC_RESTORE:
             case SC_MINIMIZE:
             case SC_MOVE:
             case SC_SIZE:
                  test = true;
                  return;
             default:
                  test = false;
                  break;
         }
}

the compiler cannot know if yuo are using the global variable test in other
code, so
can't optimize
