Subject: [PATCH] gawk: fix gensub usage
Date: Sat,  8 Aug 2015 23:48:39 -0400
Message-Id: <1439092119-24256-1-git-send-email-vapier@gentoo.org>

The third arg can either be a string with "g" or "G", or it is a number.
The empty string elicits a warning with newer versions like so:
gawk: scripts/sysd-rules.awk:56: warning: gensub: third argument `' treated as 1

2015-08-09  Mike Frysinger  <vapier@gentoo.org>

	* nptl/tst-cancel-wrappers.sh: Change 3rd arg to gensub to 1.
	* scripts/sysd-rules.awk: Likewise.
