Since Maildir (the underlying mail storage format) is not suitable for
Windows, nnmaildir.el is Posix-only.  CMIIW.

- colons in filenames; no specification about replacement charater

  (BTW, what does Samba do when `:' is used on a share?)

  nnmaildir.el could avoid hard-coding `:', though.

- no atomic rename on Windows

- (no hard links on ntfs, at least not for non-administrative users)

See <http://en.wikipedia.org/wiki/Maildir#Windows_software>.

I think a warning should be sufficient.  Maybe even only when calling
`unix-sync'.  See the attached patch.

BTW, when discussing Gnus issues, please cc <ding@gnus.org>.

Bye, Reiner.
