plugins?
Updated Cython to 0.18

3. Have you selected the option "Customize installation directories"?
NO

5. Where did you install Python(x,y) itself?
default path

6. Have you installed Python(x,y):
For "All users"
7. What is your operating system?
Windows 7

8. Is the operating system 64 bit?
Yes
but Python installed is 32bit version

9. When you installed Python(x,y), were you logged in as :
a regular user

10. If you are using Windows Vista/7, have you installed Python(x,y):
simply by double-clicking on the installer

11. Regarding installed softwares on your machine, how did you clean your
machine before installing Python(x,y) (multiple answers are possible):
 you uninstalled any previous Python distribution (including the
official .msi)

What steps will reproduce the problem?

I am trying to compile cython code. At first I tried my own code, but when 
things weren't working I tried the fib.pyx code from the Cython tutorial.
I use the setup.py from the tutorial. At first I tried compiling using the 
mingw32 compiler (I did create the distutils.cfg file to specify the mingw32 
compiler). It appears to compile -- it creates a .pyd file -- but I get some 
compiler warnings, such as "unknown type conversion character 'z'", etc. 
Compiling appears to fail because when I import and run the compiled module it 
just hangs.

According to the info on compiling 64 bit extensions 
(http://wiki.cython.org/64BitCythonExtensionsOnWindows), the mingw32 compiler 
will not work, nor is it a good idea to try the mingw64 compiler. So, following 
the suggestions at that link, I downloaded and installed the Windows 7 SDK for 
AMD64, and followed the instructions for configuring it (DISTUTILS_USE_SDK=1, 
etc). Now when I try to compile the fib.pyx code I get the "can't find 
vcvarsall.bat" error.

Do I in fact ALSO need to install Visual C++ Express 2008 for this to work? If 
so, that's a problem because it is no longer available for download.

The answer to the above issue is given inside the thread you posted - use the 
SDK compiler.

resolving this issue is beyond the scope of Python(x, y).
