# SYNOPSIS
#
# AX_CHECK_AWK__X_ESCAPES([ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
#
# DESCRIPTION
#
# Check if AWK supports \x escape codes. 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.
