+- Issue #5941: Distutils build_clib command was not working anymore because
+  of an incomplete costumization of the archiver command. Added ARFLAGS in the
+  Makefile besides AR and make Distutils use it. Original patch by David

 - Issue #2245: aifc now skips chunk types it doesn't recognize, per spec.
