You always have to link extensions with the same C runtime as Python, 
otherwise bad things might happen.

To be precise: you cannot share resources between different CRTs. E.g. 
you cannot fopen a FILE* with one CRT and fread on the FILE* with another.

If you link with a different CRT than Python, a function like 
numpy.fromfile can mess up badly.

I don't know which libraries clang link. But very likely ... if you want 
to build NumPy with clang, you also have to build Python with clang.
