 Maybe the warning is a good thing.  I object most strongly to introducing
 casts to suppress warnings, especially in libraries: casts hide bugs.  If
 you can find a way to make the warning go away without casting, I'll
 accept a patch.  Otherwise, I think the compiler may be telling you that
 you're doing something you shouldn't do, and this is not a bug in the
 library.
