[autowrap 0.6.1] using "const" keyword gives errors

[Eliasvan]

Tested with commit d0e9a5 (Feb 9, 2015). Usage of "const" causes autowrap to raise an exception.

Test code:

cdef extern from "<string>" namespace "std":
    cdef cppclass string:
        string()
        const char* c_str()

Autowrap raises following exception:

Traceback (most recent call last):

AttributeError: 'CConstTypeNode' object has no attribute 'name'

Omitting the "const" keyword solves the problem, however, then it doesn't follow the exact C definition.

this is a known issue with autowrap but since there are no "const" objects in Python, leaving out the const keyword does not change much in practice
