Yes, fair enough. I hadn't realised that while libwine is fairly small,
libwine_unicode is huge (not sure what it does, but i expect i'll find
out soon enough).

I don't really have any objection to symvers, other than it does mean
it's harder to eliminate "dead" legacy code. That's only really a
problem if the library changes fairly often though, and even then it's
not such a problem these days.
