Answer

Newer versions of gcc has better checks of types. What you see are warnings made by the compiler because some variables are declared signed vs unsigned. The logline was declared as unsigned char but the function returns char.

If you have access to SVN you should check out the 1.11 code which I still have not found time to fully finish.

Not because it is bad. It is much better than 1.10. But I have some patches I have received that are too buggy to integrate as they are and I have not had time to debug them.

See SubversionOpen2300. If you can checkout from subversion (very easy if you have the program svn installed) then you get a version which is better and should not give all these warnings and more important fixes some nasty bugs.
