Saw that last week. Just downloaded last night.

Nearly seamless.

The DB_XA_CREATE flag to db_create() was removed from the BDB api starting with
4.8.  SKS' bdb/bdb_stubs.c gets upset about it.

The 4.8 documentation says the flags value to db_create() is unused and should
be set to zero.

#defining DB_XA_CREATE to zero in bdb_stubs.c seems to be a quick fix.

4.5-4.7 -> 4.8 requires small change to SKS
