+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.
