That makes a lot of sense, thank you. Even thought it's 
counter-intuitive, because that means we not only have to care about the 
functions we call, we must also know, in this kind of situations, what 
macros expand to.

But the fact that using (autoload foo "pkg") fixes it if pkg loads 
vc-dispatcher, muddies the problem. For me, it makes compilation succeed 
without warnings not only in vc-svn, but in vc-hg and vc-cvs as well.

Unless anyone has a better suggestion (Stefan?), guess I'll just revert 
the commit.
