Optimized away was perhaps a bad choice of words. In fact, I have 
optimization turned off. It seems that the compiler just decides that 
the switch variable can never equal the cases.

I don't think I can extract a <50 line program, but this is the 
procedure in question. There are no globals that would affect this 
routine.

BTW, I tried Paolo's suggestion and added a global variable, and that 
fixed the problem!

void TMyMDIFrame::EvSysCommand(uint cmdtype, TPoint& p)
{
      // "Eat" these system commands to disable maximizing,
     // minimizing, and sizing functionality.
        uint cmd = cmdtype & 0xFFF0;
        switch (cmd)
        {
            case SC_MAXIMIZE:
            case SC_RESTORE:
            case SC_MINIMIZE:
            case SC_MOVE:
            case SC_SIZE:
                 return;
            default:
                 break;
        }
    }
    TDecoratedMDIFrame::EvSysCommand(cmdtype, p);
}
