System Details

When I try to follow the readme directions for building with Microsoft Visual C++ for x86 it fails to build with configure: error: "libffi has not been ported to i686-pc-cygwin."

In configure.host it says "try porting sys/x86/sysv.S to intel assembly format"

Also src/x86/ffi.c assumes 16-byte stack alignment for 32-bit programs but that is not true on Windows

I have a port of sysv.S for cpython that passes all of the cpython libffi test via ctypes: #468

However I don't think the autoconf changes are correct since I can't get it to build from cygwin still.

MSVC 15.9.7
