# SYNOPSIS
#
# AX_TRY_AWK_ANYOUT(NAME,TEST-INPUT,TEST-BODY,[ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
#
# DESCRIPTION
#
# Run a test using the awk program found on AWK variable. The test being
# run has TEST-BODY as body and is feeded with TEST-INPUT. If successful
# execute ACTION-IF-SUCCESS otherwise ACTION-IF-FAILURE
#
# 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.
