>Description:
While playing with recent COMPAT_LINUX32 on my -current NetBSD/amd64 machine;
i noticed that up-to-date `archivers/gtar' give some strange messages about
timestamps when extracting files :

njoly@lanfeust [tmp/tar]> gtar xvf test.tar
x
gtar: x: implausibly old time stamp 1970-01-01 01:00:00
gtar: x: implausibly old time stamp 1970-01-01 01:00:00

I made some tests and noticed that removing `patches/patch-ag' makes the
gtar messages disappear.

I'm getting the same behaviour on NetBSD/alpha running -current 3.99.10
(Wed Nov  2 11:38:21 CET 2005). In the mean time, a recent -current NetBSD/i386
machine does not show the messages ...
