My problem was that I was casting lParam to a pointer to a POINT, ie -
(POINT *)lParam.  But lParam is a FAR pointer!! So, you can just use
the symbolic constant given in windows.h LPPOINT (far pointer to tag_point
structure) to cast lParam and bingo - it works.
Sample code:
  case WM_GETMINMAXINFO:
    // to set the minimum size of the window:
    ((LPPOINT)lParam)[3].x = my_minimum_x;
    ((LPPOINT)lParam)[3].y = my_minimum_y;
    // that's it
    return 0;
Thanks again to everyone that mailed me and posted replies.  I guess I'm
too used to Unix.
