Most of them are harmless but there could be a few problems lurking
among them of course.  I don't plan to fix them myself so please send
a patch if you see any which can cause obvious problems.  Sometimes a
type conversion is necessary for the algorithm, so each case has to be
examined carefully rather than just changing the type to get rid of
the warning.
