'C:\AAA' is a volume mount point.

When run "File.realpath 'C:\AAA'" it reports:
-e:1:in realpath': No such file or directory @ realpath_rec - C:/Volume{b0513fa8-eb82-4aa7-92f4-bafb0d0d9220} (Errno::ENOENT) from -e:1:in '

ruby 2.3.0 adds HAVE_READLINK for windows then the bug appears

• win32/win32.c (fileattr_to_unixmode, rb_w32_reparse_symlink_p): volume
  mount point should be treated as directory, not symlink.

• win32/win32.c (rb_w32_read_reparse_point): check the reparse point is
  a volume mount point or not.

• win32/file.c (rb_readlink): follow above change (but this pass won't
  be used).
