+Subject: [PATCH] Fix builds with Cython 3
+
+This is a *de minimis* fix for building with Cython 3. 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`.
