| 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. |
