guix/gnu/packages/patches/python-optree-fix-32-bit.patch

In include/utils.h, ssize_t is an alias for py::ssize_t, which is an alias for
Py_ssize_t in Python, which is an alias for the system ssize_t.
The latter is defined in glibc as int if __WORDSIZE == 32 and as long int if
__WORDSIZE == 64.  Therefore, we need to remove the explicit template
specialization for int in the first case.
