This should be fixed in libol 0.2.15 and syslog-ng 1.3.16. I didn't backport
the fix to 1.2.4 (which I've just released), because it's not trivial.
I've fixed a couple of build fixes, so syslog-ng should build cleanly on the
Solaris 2.5.1 or lower (without door support)
Solaris 2.6 or upper (with door support)
I would be grateful if you could check this.
