Sorry if I don't get your problem.  The resulting path is correct, isn't
it?  Cygwin handles junction points as symlinks.  When creating
a Windows path, symlinks get resolved, since native Windows applications
(the target audience for cygpath -w) don't understand symlinks.

"Faulty" is a bit harsh, isn't it?  The target audience for `cygpath -u'
are POSIX apps which *do* understand symlinks, so it's not necessary
to resolve them.

Sure.  Otherwise it's not possible to create DOS paths from POSIX paths
for yet-to-be-created files.
