* 1999/10/23 acme cycxhw_t cleanup
* 1999/01/03 acme more judicious use of data types...
* uclong, ucchar, etc deleted, the u8, u16, u32
* types are the portable way to go.
* 1999/01/03 acme judicious use of data types... u16, u32, etc
* 1998/12/26 acme FIXED_BUFFERS, CONF_OFFSET,
* removal of cy_read{bwl}
* 1998/08/08 acme Initial version.
