[Ludovic Courtès]

civodul pushed a commit to branch stable-2.0
in repository guile.

commit 9a4215b8c2a38d01931f0ddcb58657085c69d915
Author: David Michael <address@hidden>
Date:   Wed Jul 22 12:48:24 2015 -0400

    Fix the rule to check for new signals and errors
    
    Fixes <http://bugs.gnu.org/21114>.
    
    * 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.
