Hi,
the attached patch adds a configure check for openlog, and changes the
greeter code to use #ifdef HAVE_OPENLOG instead of __OpenBSD__. I don't
know if additional checks for <syslog.h> or LOG_AUTH are needed, though,
but that should be easy to fix if necessary.
Cheers,
Julien

Subject: [PATCH] Add support for syslog on more than openbsd.
Also use LOG_AUTHPRIV by default, if that exists.
