Bug#102191: libstdc++2.10-dev has unset $pkg_ver in prerm

[Adam Heath <doogie@debian.org>]

package: libstdc++2.10
version: 1:2.95.2-14

yakko:/mount/md0/mirror# cat /var/lib/dpkg/info/libstdc++2.10-dev.prerm
#! /bin/sh -e

if [ \( "$1" = "upgrade" -o "$1" = "remove" \) -a -L /usr/doc/libstdc++2.10-dev ]; then rm -f /usr/doc/libstdc++2.10-dev; fi


install-info --quiet --remove iostream$pkg_ver

--

Note how $pkg_ver is not set.  Looking at the postinst, there is a value, and
no variable.  This appears to be a problem with some file munging in
debian/rules, but I haven't checked there.
