Thanks!  Patches to fix these problems are always appreciated.

Storing integers within pointers is safe, isn't it?  Compare:

How large is 'int' on your platform?  How large is 'void*'?

This looks like a pure bug to me.  Nikos?

I didn't go through all warnings.  If we resolve these, we can move on
to the others.  Chances are that fixing these may fix some of the
others too.
