Hi,
after reading of ustar format
(http://www.gnu.org/software/tar/manual/html_section/Formats.html)
I have made patch for m4/tar.m4 file against upstream:
In case that ustar format is used and uid or gid is bigger than 2^21
than configure will always failed
Patch is:
diff --git a/m4/tar.m4 b/m4/tar.m4
index ec8c83e..1eca282 100644
--- a/m4/tar.m4
+++ b/m4/tar.m4

Please review it and let me now whether something is wrong.
If something will be wrong I will make a correction.
Tests where performed as on big uid as on big gid and both.
I have been looking for making test in that case, but found that useradd
binary should be called
and I think that we do not what to do that.
