Friends,

comparators usually take arguments like

(const void *a, const void *b)

and do something read-only to a and b. In our
sources, we typically cast these to something else,
like (char *), and do something read-only. This
generates a lot of warnings if using -Wcast-qual.
To fix that, I have converted the casts to not cast
away const. Please find my changes, attached.
