Get NumPy to Compile

Things needed to get NumPy to compile

Cython

Debug this Cython assertion. NumPy needs Cython to generate mtrand.c from mtrand.pyx and we can't just use the regular Cython because we need to apply Marius' patch (if we don't, mtrand.c won't compile.)

```

python: ../../src/asm_writing/rewriter.cpp:1617: assembler::Register pyston::Rewriter::allocReg(pyston::Location, pyston::Location): Assertion `vars_by_location.count(best_reg) ==

0' failed.

Traceback (most recent call last):

```

PyStringObject and PyStringScalarObject

Need to access the fields of PyStringObject directly and do sizeof(PyStringScalarObject) which is just a typedef for PyStringObject, currently just forward declared. More specifically, fields include ob_shash and ob_sstate.

Descriptors

NumPy looks at the PyDescr_ objects in descrobject.h

Compiler Crash

Why is this crashing the compiler? (ufunc_object.c)

fail:

// Causes compiler error wtf

for (i = ufunc->nin; i < ufunc->nargs; i++) {

Py_XDECREF(mps[i])

}

return NULL;

}

Misc

Need to define SIZEOF_SHORT
