Problem with buffer/memview parsing strategy

[dagss]

gsoc-kurt branch

In Parsing.py it says:

# (This means that buffers/memviews cannot occur where there can be empty
# declarators, which is an ok restriction to make.) 

However, this may not be the case. Empty declarators can occur in cdef functions, like in this extern case:

cdef extern foo(int[])

Hence, current parsing code don't understand

cdef foo(int[:]): ...

I've updated TestMemView?.py with a testcase that highlights the problem. A likely fix involves not depending on (or better set) nonempty in p_c_simple_base_type.

Adding tests to TestMemView? ensuring that cdef foo(int[]) as well as sizeof(int[4]) still works would be good too.
