[SciPy-dev] Scipy weave error with mingw-3.4.5

[Christopher Galvan]

Hello,

I was trying to run an example I found of compiling C code into a python 
module.  I have attached the .py file I ran.  The resulting error was 
given when I was using MinGW-3.4.5, but the process ran fine on 
MinGW-3.2.3.  Is there some kind of compatibility issue that I am 
missing?  Any help would be greatly appreciated.
