So this is a case where Cygwin fails to emulate *nix behavior.  I assume
it works correctly on various *nix implementations.  You may consider
that a Windows issue, but if the purpose of Cygwin is to provide a
porting environment, then that's a shortcoming of Cygwin. 

The mutt developers aren't particularly concerned with Cygwin or
Windows, so they don't regard this as an issue.  I don't see why this is
a mutt problem.  They assume that stat() works correctly.  I'm not sure
who's responsible for the Cygwin build of mutt, or for including it in
Cygwin at all, but that's something to be considered in the future. 

I'm guessing there's no problem with mbox mail folders, since they're
just ordinary files.  The problem comes in because maildir and MH
formats us directories as mail folders. 

BTW, if anyone knows how to build mutt under Cygwin, I'm *dying* to find
out.  I can work around the stat() problem, but I have not succeeded in
building a mutt for Cygwin that doesn't crash on opening certain
messages. 

Thanks,
