ChangeLog

+2014-02-25  Mike Frysinger  <vapier@gentoo.org>
+	* src/Makefile.am - Rename 'INCLUDES' to 'AM_CPPFLAGS', since
+	Automake changed the naming of these a while ago, and at least
+	version 1.13 now starts warning about it.
+
 2014-02-25  Benno Schulenberg  <bensberg@justemail.net>
 	* src/files.c (write_lockfile, do_lockfile) - Fix a typo reported
 	by Jean-Philippe Guérard and inconsistent spelling of "lock file"
