  15 * 1999/10/23    acme            cycxhw_t cleanup
  16 * 1999/01/03    acme            more judicious use of data types...
  17 *                               uclong, ucchar, etc deleted, the u8, u16, u32
  18 *                               types are the portable way to go.

  20 * 1998/12/26    acme            FIXED_BUFFERS, CONF_OFFSET,
  21 *                               removal of cy_read{bwl}
  22 * 1998/08/08    acme            Initial version.
