Can't compile Cython function with multiple input arguments - cython

Question

I am trying to get Cython running and I think I'm almost there but have hit a snag that I do not understand. I can compile functions with a single argument, but not with multiple. I have this issue with python 3.3, but not 2.7.
I successfully compiled and ran "hello world" and fibonacci examples but when I try to compile anything with two or more input arguments I get an error when compiling.
To boil it down to a very simple case. This compiles, imports to python, and runs.
def cycheckadd(c):
b = 1
d = b + c
return d
This does not.
def cycheckadd(b,c):
d = b + c
return d
And returns the following error when building.

Compiled using the setup.py file below.
from setuptools import setup
from Cython.Build import cythonize
setup(
name = 'cython math check',
ext_modules = cythonize("cycheck.pyx"),
)
This result was generated using python 3.3 and cython 0.22. I do not have this problem when I use 2.7.
The compiler is MinGW. I have been using 32bit versions of Python on Windows 10-64bit. I have added the following config file to the python directory.
C:\WinPython-32bit-3.3.5.9\python-3.3.5\Lib\distutils\distutils.cfg
[build]
compiler = mingw32
[build_ext]
compiler = mingw32
Any help would be greatly appreciated!
Thanks,
Chris
