Do you mean the .lnk (a.k.a. shortcut) files?  If so, I wouldn't call
them symlinks, not even restricted ones.  As long as most file I/O
APIs don't follow links, we are better off behaving as if there are no
symlinks at all.

Sorry, I don't follow: what mount points?

The best way to prepare for symlinks in Vista is to have a realpath
emulation somewhere in w32/ subdirectory.  Then we could define
HAVE_REALPATH in config.h.W32 and things will ``just work''.

I don't have access to a Vista machine, so I won't be able to test
symlink support.
