Environment: Mips M/120 running Riscos/5.00 using Mips 3.0 compilers
	and  Sun SparcStation 2 running SunOS 4.1.x using gcc 2.2.2

Chown does not work on (at least some) machines that have non-`int'
uid_t and gid_t types (e.g., ones where uid_t is an unsigned short).
This is because parse_user_spec() expects pointers to [ud]id_t's but is
passed pointers to int's.  The following diff fixes chown.c to use the
correct types when dealing with uids and gids.

[BTW: The diff I recently sent for dd.c is backwards (i.e., generated
      by diff -c newfile oldfile).]
