That is rather old code, before 2008, inherited from SER, related to those custom config parameters that can be set during runtime. I looked once at them, but could get to a decision on how to fix it, because it is relying a lot on defines -- I would need more time and a system which throws those errors, my versions of gcc are not showing them.

short note to remind about upcoming release of Kamailio v4.3.0 -- I am planning to get it out tomorrow, pretty much everything is prepared for it and not major issues were reported lately.
this is probably not a major issue, but it sure looks ugly. some do say that compiler optimizations may actually break the code. i was not able to figure out a fix.
