Since the Subversion project doesn't "officially" produce binaries, I
don't think there's any need to make this sorr of promise. Which
dependencies get used in the build is really up to the package
maintainer, and will generally depend on which version of Apache is
normally part of a particular distribution.

I think we expose apr_off_t in the some function signatures. I agree we
should fix that in a 2.0 release.

Heh. Saying "Subversion" here is a bit misleading. The thing that works
with apache is mod_dav_svn, but that links with several of the
libraries. Certainly the client doesn't have to use the same APR version
as the server (except for file:// access)

It's always good to spell these things out.
