The type of new_value is either `npy_timedelta' or `int64_t'
In build/pandas/_libs/tslibs/timedeltas.cpython-313-x86_64-linux-gnu.so.p/pandas/_libs/tslibs/timedeltas.pyx.c
..
npy_timedelta __pyx_v_new_value;
...

In build/pandas/_libs/tslibs/timedeltas.cpython-313-x86_64-linux-gnu.so.p/pandas/_libs/tslibs/timedeltas.pyx.c
...
__pyx_t_5numpy_int64_t __pyx_v_new_value;
...

Explicitly define it as int64_t to assure the generated source is
reproducibility between builds
