* notes:
* - tc_xvid_ prefix is used to avoid any possible name clash with XviD code
* - export_xvid4.c was a really nice and well-written module, this module
* is largely based on such module and share a large portion of code with
* it. So hopefully it should work nicely :)
* - handling of dynamic loading of further shared objects (XviD codec, here)
* isn't optimal, such details should be handled by libtc.
* libdldarwin too should be merged with libtc, or maybe we should switch
* to libtool wizardry.
