PyBool_CheckExact not defined in c code for python 2.5.4.

[hoytak]

Hello,

I'm using the latest pull from cython-dev, 1800:e8b5a8e5da3d, with python 2.5.4, and some of my code calls PyBool_CheckExact(). However, this doesn't seem to be defined anywhere. When I compile it with gcc, it warns that the symbol is defined implicitly, and trying to load it results in an import error saying it's an undefined symbol.

The simplest code I could find that uses PyBool_CheckExact() is:

cdef foo(bool a):
    assert a == True

def test():
    foo(True)

It seems that there's some issue in using the bool type; if the bool above is replaced by bint, the code works fine.
