  Okeydokey.  Upstream libffi generates cygffi-6.dll, so what I'll do is
incorporate the patch (along with your others) into 4.7.3-1 (which will be a
full curr: version release), and ship one last version of libffi4 (marked
obsolete) with that but make sure the man pages, static import lib etc (-devel
stuff basically) is not packaged.  That'll probably be in ten days or so, at
which point you can upload the standalone libffi.  Makes sense?
