The first step is to patch Makefile.cygwin to define ARCH 
using the script, thus:

--- Makefile.cygwin.orig        2014-04-18 13:09:05.398891100 -0400
+++ Makefile.cygwin     2014-04-18 13:09:26.715110300 -0400

 # platform configuration

-ARCH ?= x86
+ARCH ?= $(shell sh $(SRCDIR)/

That's more reliable than setting ARCH yourself.

Then you need to change the #ifndef in apply-hack.x86-64.S to suppress
the .type declaration on non-ELF platforms, which include both Apple
and Cygwin64, thus:

--- apply-hack.x86-64.S.orig    2014-04-18 13:12:09.893443600 -0400
+++ apply-hack.x86-64.S 2014-04-20 15:40:43.025428300 -0400

        .globl _C_do_apply_hack
-#ifndef __APPLE__
+#if defined(__ELF__)
        .type _C_do_apply_hack, @function

But after that you still get a linkage failure, so you are on your own.
Right now there are enough other packages that Cygwin64 doesn't support
that I decided to revert to Cygwin32, which works fine even on Woe64.
