Not a > bug, not worth wasting time on. The potential for "real problems" was my main reason for pointing it out. I ran some (unrelated) tests on Fedora Rawhide (fc19) with clang 3.2 RELEASE and gcc 4.8.0 and this issue popped up as -Wall -Werror was used for the project in question. The two lines mentioned are the only issues encountered. If it is worth "fixing" or not I leave up to you to decide, I merely wanted to highlight the potential issues.
