AX_CHECK_AWK_CONDITIONAL_EXPRESSION([ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
@end smallexample

@majorheading 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.
