[Lars Ingebrigtsen]

branch: master
commit 53720a9bdedaf75eebf199897740561a4040b5c4
Author: Dima Kogan <dima@secretsauce.net>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    gcc-include compilation lines are now INFO, instead of WARNING
    
    * lisp/progmodes/compile.el
    (compilation-error-regexp-alist-alist): Prior to this patch the
    line that contains "from a.h:1:0," was seen as INFO and the line
    that contains "from a.c:1:" was seen as a WARNING.  This patch
    makes them both INFO (bug#17826).
