# SYNOPSIS
#
#   AX_CHECK_AWK_CONDITIONAL_EXPRESSION([ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
#
# DESCRIPTION
#
#   Check if AWK supports conditional expression (e.g. x = y ? 5 : 6). 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.
