This patch fixes several problems: it fixes incorrect or incomplete error
 messages; it fixes a problem opening the SQLite3 database when multiple
 simultaneous jobs were running; it fixes a bug with certain versions of
 MySQL where batch inserts failed because of table name character case
 (upper/lower) differences.

 It can be applied to version 2.2.4 (and possibly earlier 2.2.x versions)
 with:

   cd <bacula-source>     
   patch -p0 <2.2.4-sql.patch
   ./configure (your options)
   make
   ...
   make install
