Rich Felker 9ae8d5fc71 fix all implicit conversion between signed/unsigned pointers
sadly the C language does not specify any such implicit conversion, so
this is not a matter of just fixing warnings (as gcc treats it) but
actual errors. i would like to revisit a number of these changes and
possibly revise the types used to reduce the number of casts required.
