There's a dilemma here, known as "Windows DLL hell". Since we have no
control over installations, we can't prevent somebody from _downgrading_
the installed DLLs. If the DLL names in svn-1.x are the same as in
svn-1.x+1, the newer stuff will break.

Come to think of it, I think we should even encode the runtime version
in the DLL name, so that a program compiled with VS.NET won't pick up
DLLs created with MSVC6 by mistake.
