-From 3da25ddd011c169b9857ed2f6a2e82988f059ba5 Mon Sep 17 00:00:00 2001
-From: Mike Frysinger <vapier@gentoo.org>
-Date: Fri, 3 Apr 2015 02:39:21 -0400
-Subject: [PATCH] make perl & examples optional
-
-The normal bison program does not require perl to build or run, so lets
-soften that requirement in the configure script.  We now warn if its not
-found, and we make the examples logic depend on that.
-
-* configure.ac: Change AC_MSG_ERROR to AC_MSG_WARN for perl.
-Add an --enable-examples flag.
-* Makefile.am: Only include examples/local.mk when ENABLE_EXAMPLES.
