Bug#204827: dpkg-dev: dpkg-parsechangelog fails with _POSIX2_VERSION=200112

[Colin Watson <cjwatson@debian.org>]

Package: dpkg-dev
Version: 1.10.10
Severity: normal
Tags: patch

dpkg-parsechangelog uses 'tail -40' to find the changelog format.
However, options like -COUNT to tail are obsolete, and disallowed if
_POSIX2_VERSION=200112 is set in the environment; see
http://lists.debian.org/debian-glibc-0308/msg00120.html for more
discussion and information.

A patch fixing this is attached.

Thanks,
