Subject: bug#21114: [PATCH 1/4] Fix the rule to check for new signals and errors
Date: Wed, 22 Jul 2015 12:48:24 -0400

* .gitignore (/libguile/*.NEW): New pattern.
* libguile/Makefile.am (chknew-E chknew-SIG): Remove the line
  continuation after the targets, and include numbers in the
  recipe's signal/error regexp to catch names like E2BIG.
---


This patch series makes a few updates to the generation of the lists of
signal and error signals.  This first one makes the chknew targets work
again.  GNU Make says there is no such target without this.
