pyximport and distutils directives

[Antony Lee]

I *believe* that pyximport is not obeying distutils directives at the top of a pyx file.

Examples:

#distutils: language=c++

cdef extern from "<cmath>":

    T fabs[T](T)

def f(x):

    return fabs(x)

==> fails to compile as it calls gcc instead of g++

#distutils: undef_macros=NDEBUG

cdef extern from "assert.h":

    void cassert "assert"(bint)

def g():

    cassert(0)

==> g() does not lead to an assertion failure.

While pyxbld files could help, I feel putting everything in a single file is easier to maintain (and they aren't even mentioned in the Cython docs).

You are correct, you might have seen:

I'm not using pyximport any more so I never got around patching it.
