-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`.
-
-Signed-off-by: Andrew J. Hesford <ajh@sideband.org>
