Recent Cython<3 +releases provided `Cython.Distutils.build_ext` as an alias to +`Cython.Distutils.old_build_ext.old_build_ext`; Cython 3 drops this +alias and instead uses a wholly new `Cython.Distutils.build_ext` that +does not provide the `cython_sources` function used in `setup.py`. + +Explicitly importing `old_build_ext` preserves the existing behavior for +recent Cython<3 and uses the correct behavior for Cython 3. Should the +import fail (*e.g.*, because the version of Cython available predates +the availability of `old_build_ext`), the import falls back to just +`Cython.Distutils.build_ext`. + +Signed-off-by: Andrew J.
