You should put the extern block around the #include <python.h> call
rather than individual functions, as surely the C calling convention
should apply to everything within.

More of a Visual C++ question specifically, since the __clrcall prefix
is a MS specific extension (http://msdn.microsoft.com/en-us/library/
ec7sfckb(VS.80).aspx). If you're not using managed code in your app,
disable it in the project/build options. If you are, then perhaps you
just need to specify that you're not with this DLL, though I've never
had to deal with anything like that myself.
