Squid not working w/ latest master

[Jan Lentfer]

After updating my router to v2.7.3.1047.gc520c9-DEVELOPMENT Squid 
doesn't work anymore (I am talking about standard mode, not transparent).
The squid process starts and then it just sits there. I have to kill the 
processes to shut it down again, doesn't work from rc script.
Port 3128 is open and I connect to it with telnet, just squid doesn't 
handle any of the requests. Squid works fine with 
2.7.3.1090.g20045-DEVELOPMENT.
