Both functions are never used, so let's get rid of them.

Because it's dead code.  Looking again, it actually seems correct
after all :-) (void_ptr_hash_function() is passed in a pointer *value*,
which is then stored locally, and the address of this local store is
handed to hash_func() - so it compares "memory addresses".  Misread the
code before.  It's James code so it must be correct.  But unused still!

Your patch has been applied to the master branch.
