python - How to Install M2crypto on Windows

Question

After installing OpenSSL, downloading the pre-built Swig executable, and ensuring the openssl libraries are located in the default c:pkg, pip install m2crypto results in:

...
C:Program Files (x86)gfortraningcc.exe -mno-cygwin -mdll -O -Wall -IC:Pyth
on27include -IC:Python27PC -Ic:pkginclude -Ic:usersevboappdatalocalem
ppip_build_evbom2cryptoSWIG -c SWIG/_m2crypto_wrap.c -o buildemp.win32-2.7
Releaseswig\_m2crypto_wrap.o -DTHREADING

gcc: error: unrecognized command line option '-mno-cygwin'

error: command 'gcc' failed with exit status 1

It seems the binary installer solution for M2crypto is no longer available and I don't see any mistakes I've made based on the M2crypto install doc.

How might I resolve this install issue? Is there a dependency on older versions of GCC?

I got lucky - there's an unofficial binary installer in lieu of chandlerproject.org/bin/view/Projects/MeTooCrypto being down:
