There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.
Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

Instead use %ju and cast the argument.
WFORMAT=0 is still required in the Makefile because gcc warns about
some strftime() calls (I don't think this behaviour is useful.)

* Implement cpio compatibility mode when pax is invoked as cpio
* Extend tar compatibility mode to cover many of the GNU tar single-letter

* Many bug fixes to the operation of pax and the tar compatibility modes
* Code fixes for things like correct string buffer termination.
I tried to preserve existing FreeBSD fixes to this utility; please let me
