Subject: bug#13588: Pax hangs in case big UID
Date: Wed, 30 Jan 2013 14:31:11 +0100

Dear folks,

I am trying to solve problem in case that user is created with big UID
and during configuration pax hangs and need user interaction.

Last list are:
http://lists.gnu.org/archive/html/bug-automake/2011-11/msg00014.html
https://bugzilla.redhat.com/show_bug.cgi?id=843376

Below patch to my previous correction
http://lists.gnu.org/archive/html/automake/2013-01/msg00079.html

It checks also command id whether it exists.
If id does not exists on (not Linux system) then we do not care about that.

Patch is bellow and against upstream:
