-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.
