# SYNOPSIS
#
#   AX_NEED_AWK
#
# DESCRIPTION
#
#   Check if an awk implementation is available. Bail-out if not found.
#
#   This work is heavily based upon testawk.sh script by Heiner Steven.
#   You should find his script (and related works) at
#   <http://www.shelldorado.com/articles/awkcompat.html>. Thanks to
#   Alessandro Massignan for his suggestions and extensive nawk tests
#   on FreeBSD.
