{AJ} The GNU C library 2.1 uses db2 instead of db1 which was used in version
2.0. The internal formats of the actual db files are different. To convert
the db files from db1 format to db2 format, you can use the programs
`db_dump185' and `db_load'. Alternativly programs can be linked with db1
using `-ldb1' instead of linking with db2 which uses `-ldb'. Linking with
db1 might be preferable if older programs need to access the db file.
db2 supports the old db1 programming interface and also a new programming
interface. For compilation with the old API, <db_185.h> has to be included
(and not <db.h>) and you can link with either `-ldb1' or `-ldb' for either
of the db formats.
