Comment 1 for bug 986611

Based on widelands r6346 (with a few additional fixes not yet merged) and cppcheck 1.54.

Note that while generating your own report will list roughly ~40 more issues, but these already have suggested patches, so please don't waste your time doing duplicate work.

Also note that cppcheck 1.49-1 (at least in Ubuntu 11.10) will list all issues each time it finds it, while later versions only lists each issue only once. Without the duplicate lines, the report is a lot less noisy and easier to read. (The difference was ~260 vs ~12000 lines)
