Currently, the examples are extracted on the user's side. Unfortunately, that requires that the user has Perl, which is otherwise not needed for Bison. Let's ship the examples instead. The examples were handled this way so that we could depend on configure flags: if --enable-gcc-warnings is passed, it is understood as "I'm a maintainer", so the examples are generated with `#line`s. Regular users should not see them, so they are now unconditionally removed when rolling a tarball. Reported by Mike Frysinger. https://lists.gnu.org/archive/html/bison-patches/2015-04/msg00000.html * examples/local.mk: Ship all the extracted files. (examples-unline): New. Make sure that the generated tarballs do not contain the #lines.
