Bump PKGREVISION.
Some key changes:
* configure.in: changed "source" to "." as the source command is a
bashism, changed a couple of double equal signs to single ones,
moved libol to the statically linked libs as AIX links to .a files
dynamically unless static linking is explicitly requested
* src/filters.c (do_filter_netmask): fixed negation for the
netmask() filter
* src/macros.c: added LEVEL_NUM and FACILITY_NUM macros
