14* ============================================================================
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.
