Hello,

Via doing an impact check for the latest Cython 3.2.0, python-giacpy failed to build from source.

Snippet:

File "../../giacpy/giacpy.pyx", line 266, in giacpy.pyx
Failed example:
    A[0][0]=A[0][0]+1; A  # similar as A[0,0]=A[0,0]+1
Exception raised:
    Traceback (most recent call last):
      File "<doctest giacpy.pyx[54]>", line 1, in <module>
        A[0][0]=A[0][0]+1; A  # similar as A[0,0]=A[0,0]+1
        ~~~~^^^
      File "giacpy/giacpy.pyx", line 1027, in giacpy.giacpy.Pygen.__setitem__
    TypeError: Expected bool, got int
Trying:
    A.pcar(x)  # compute the characteristic polynomial of A
Expecting:
    x**2-48*x+170

Full build logs can be found here: https://copr.fedorainfracloud.org/coprs/cstratak/cython-3.2.0/package/python-giacpy/

The issue can be fixed with this patch, as Cython now explicitly expect a bool to be true:
