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.
