Recently (possibly with an upgrade to emacs 24.1.1) I'm frequently getting this message:
    Error reading dir-locals: (file-error "Opening input file" "not a directory" "/cygdrive/q/.../tlock.c/.dir-locals.el")

I see this frequently (but not always) under Cygwin and never under AIX 6.1.

I do, of course, hack emacs, but I can't think of anything I've done that might have to do with dir-locals. Except for X configuration, I use exactly the same code on AIX and Cygwin.

Since the obvious question is too vague, I'll simply ask this:
    Does anyone have any thoughts about this?

Thanks.
