Unfortunately this commit only deals with tar archives in (old) GNU
format, not with POSIX tar archives (which were only described later in
POSIX.1-2001, according to the GNU tar info docs).

It still is, actually. I took the steps to extract and uncompress the
data.tar from Mathieu's archive, and file reports it as “POSIX tar
archive”. However, tar currently does not create POSIX archives by
default; when I repacked the data.tar, file said “POSIX tar archive
(GNU)”. Then I reassembled the .deb with ar, and dpkg installed it
correctly. It is attached for reference.
Mathieu, how did you create the deb? Do you have TAR_OPTIONS set so
that tar creates POSIX archives?

Especially as tar will switch to creating POSIX archives by default some
day. We should also try to assure that dpkg-deb creates GNU tar
archives until the dpkg in the stable Debian release supports POSIX tar
archives with filenames > 99 characters.
There are files with that long (> 100 characters) names in the archive;
to see some of them, download and unzip (e.g.) Contents-i386.gz and run
the following script on it to sort it by line length (needs several 100
Megabyte RAM; beware!):
--8<---------------cut here---------------start------------->8---
#!/usr/bin/perl
my @lines = <>;
print reverse sort { length($a) <=> length($b) } @lines;
--8<---------------cut here---------------end--------------->8---
Pipe this through head -n 1000 or something like that and enjoy.
Cheers,
