Test failure on Windows

Start with tests.py and reproduce test_codegen on Windows using the reported setup.py configuration. Compare the generated signature with the expected value and inspect echoprint.cpp plus the listed libcodegen sources to identify the platform-dependent difference; done means the test passes with the intended signature on Windows.

I've been able to compile echoprint extension with MSVC after these patches:

However test fails:

My compile generates signature with 245 characters, while test asserts equal signature with length of 145 characters.

Can someone point the reason for this failure?

Thanks
