Windows ACLs don't have exec bit in the UNIX sense.

It does not work on NTFS either. For all the same reason I described
above: Cygwin tries to be clever (and annoying) and looks into files.
And no Windows program (like, for example, your editor of preference)
will call Cygwin's chmod just to set the permissions how Cygwin likes
them.
