compiling bbdb3 with mingw

Roland Winkler added `makefile-temp' to the lisp directory of the
development version of BBDB for those without Autoconf-2.69, say those
of us MinGW users.

I've tried this,

cd bbdb/lisp
make --makefile=makefile-temp

and got,

/bin/cp bbdb-site.el.in bbdb-site.el
/bin/rm -f bbdb-loaddefs.el;
LC_ALL=C emacs --batch --directory=./  -l autoload \
                --eval '(setq generated-autoload-file "'`pwd`/bbdb-loaddefs.el'"
)' \
                --eval '(setq make-backup-files nil)' \
                -f batch-update-autoloads `pwd`

[I've tried messing around with makefile-temp to get rid of this:]

Opening output file: no such file or directory, c:/c/bbdb/lisp/bbdb-loaddefs.el
                                                ^^
LC_ALL=C emacs --batch --directory=./  -f batch-byte-compile bbdb-site.el
Wrote c:/bbdb/lisp/bbdb-site.elc

[...]

LC_ALL=C emacs --batch --directory=./  -f batch-byte-compile bbdb-ispell.el
Wrote c:/bbdb/lisp/bbdb-ispell.elc

But alas, cannot successfully produce `bbdb-loaddefs.el', only,

(provide 'bbdb-loaddefs)
(if (and load-file-name (file-name-directory load-file-name))
    (add-to-list 'load-path (file-name-directory load-file-name)))

gets written.

make --makefile=makefile-temp EMACS=/c/path/to/bin/emacs

was suggested to me, but I got the same path noted ^ above.

Any MinGW aficionados?
