There doesn't appear to be one in my (freshly sync'd) copy:

grep -r lstat gnulib
gnulib/Makefile.in:localstatedir =3D @localstatedir@

If objfile->name is "/foo/bar/baz", and is a symlink to "/zork/zark/baz"
(and nothing else is a symlink) then the two realpath() calls will return
"/foo/bar" and "/zork/zark/baz" and (I think) are unavoidable.
