cool, and thanks for testing the fix. if syslog-ng 1.5.23 proves to be
stable, I'll release 1.6.0

Could you - not specifically you, rather the list - please test the
configure.in changes as well on different platforms?

I've tested it on Debian GNU/Linux, and Solaris 8 (Linux on x86, Solaris on
Sparc).

A test on one of the BSDs and HP-UX would be welcome.
