  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.
  19* 1999/01/03    acme            judicious use of data types... u16, u32, etc
  20* 1998/12/26    acme            FIXED_BUFFERS, CONF_OFFSET,
  21*                               removal of cy_read{bwl}
  22* 1998/08/08    acme            Initial version.
