AX_CHECK_AWK_ENVIRON([ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
Check if AWK supports ENVIRON variable. 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.
