Unfortunately, the 4th patch is the one that needs rework.

Unless someone ever invents a system with 64-bit uid_t (to date, no one
has - your claims about u64 to the contrary), treating 4294967295 as
(uid_t)-1 is safe.  POSIX already guaranteed that (uid_t)-1 cannot be
used as a valid user id.

Did you run 'make check' on your patch?  We already have XML output that
is affected by the change in output format, and can write the test so
that we prove that multiple ways of formatting input all get
canonicalized to the same output.
