Re: cross-compile alien

[Fabio Mascarenhas <mascarenhas@...>]

You should use Makefile.win as a base (making the necessary changes to
work with the GNU tools in your cross-compilation toolchain) instead
of the regular Makefile. Building libffi for Windows does not use
configure && make, but uses the patched version of libffi in the win32
directory directly.
