I'd suggest to use libltdl (part of libtool), which will make these
features more portable.

Note that the GNU project's practice for plugins is to require that
any compatible plugin exports a symbol named plugin_is_GPL_compatible,
to signal that it's released under GPL or a compatible license.  I
think any framework should have the verification of this as its part.

Thanks.
