** Description changed:
The only feature used by dpkg-awk beyond those required by POSIX is
'delete array'. This extension is supported by all awk variants
currently in Debian, i.e. by gawk, mawk, and original-awk. Attached diff

installed by package 9base as /usr/lib/plan9/bin/awk and doesn't provide
awk in Debian.
But if POSIX compatibility must be retained by all means, the following
patch should also be applied. It replaces 'delete array' with
'split("",array)'. In this case, 'unset POSIXLY_CORRECT' in /usr/bin
