Subject: id bug fix: don't point to potentially clobbered static storage
X-Git-Tag: v6.11~56

id bug fix: don't point to potentially clobbered static storage

On at least Mac OS, when calling getpwuid twice with the same UID,
the static storage containing results from the first call is
invalidated by the second call.
* src/id.c (main): Point to a copy of the user name string.
