Building a dependency library regularly causes issue e.g. on Windows.
I know there are reasons to hate it very much, but IMHO for core features
at least allowing to use svn:external variants is highly useful, both for
making it easy for users to build with (a current version) of this feature
as well as making it easier to do debugging/bug fixing.

I think this is a very bad idea.
Particularly since I don't really see a reason for it, almost all of the
CONFIG_ASS #ifdefs in the vos adds code bloat (in addition to removing EOSD)
for no good reason at all.
I don't think the vos should depend on any structs from libass if that is the issue,
these should be converted in some MPlayyer-specific code if neccessary, otherwise
we risk that a single incompatible API change in libass means you have to change
code in all EOSD-capable vos instead of one single place.
