[syslog-ng]-u and -g switches on syslog-ng 1.5.6

Hi! I tried to run my newly-compiled syslog-ng-1.5.6 with different user and group values than usually (root). As trying it, got segfault several times, so after a short time I discovered some silly coding in src/main.c. In order to make it work, only _really_ simple changes have to be made, I also made a diff-file of the release and my (working) source. I attach it. Hope I got the problem right, and didn't get messed up :) sci -- Murvai-Buzogány László Laszlo.Murvai-Buzogany@gt-systems.hu
