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)\gfortran\bin\gcc.exe -mno-cygwin -mdll -O -Wall -IC:\Pyth
on27\include -IC:\Python27\PC -Ic:\pkg\include -Ic:\users\evbo\appdata\local\tem
p\pip_build_evbo\m2crypto\SWIG -c SWIG/_m2crypto_wrap.c -o build\temp.win32-2.7\
Release\swig\_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:

https://github.com/saltstack/salt-windows-install/blob/master/deps/win32-py2.7/M2Crypto-0.21.1.win32-py2.7.msi
