Bug#191669: xserver-xfree86: _POSIX2_VERSION=200112 upgrade failure (+ patch)
Package: xserver-xfree86
Version: 4.2.1-6
Severity: normal
I have _POSIX2_VERSION=200112 set in my environment; this causes some
GNU utilities (notably coreutils 5.0) to conform to the new POSIX
standard rather than the old one. The new standard disallows
obsolescent usages like "head -1"; you're supposed to use "head -n 1"
instead. Setting this variable caused "dselect" to fail when
attempting to upgrade to xserver-xfree86 4.2.1-6, with the following
symptoms. I enclose a patch at the end of this message.
To reproduce the problem, set _POSIX2_VERSION=200112 in your environment
and then attempt to upgrade to 4.2.1-6.

Here is a proposed patch. I haven't tested it -- it's done only by
inspecting the code looking for problematic uses like "head -1".
