nnmaildir renaming error

[Jimmy Pritts]

Does the nnmaildir package work with xemacs under cygwin?  I am
running Windows XP and a recent Cygwin.

I am trying to use the nnmaildir package with gnus under Cygwin.  I
have fetchmail feeding messages to procmail which delivers mail to
~/.nnmaildir/mail.misc.  Under mail.misc I have the standard
directories: new, cur, and tmp. When nnmaildir tries to read the mail
from mail.misc, it reports and error when trying to rename the file. 
For example, if the file is "~/.nnmaildir/mail.misc/new/foo", gnus
will try to move it to "~/.nnmaildir/mail.misc/cur/foo:2" but will
fail.  I don't think colons are allowed with Windows, maybe this is
the problem?

Any help would be much appreciated.

Thanks.
