+This patch removes sources of build non-determinism in the upstream sources.
+
+In particular, many of the compiled sources are generated with Python code,
+which in turn uses dictionaries to index the output C functions.  However,
+iterators over Python dictionaries have no guaranteed order, thus resulting in
+the C functions being output in a random order between builds.
+
+The patch below fixes this by forcing an order during output in several key
+places.  Note, however, that future updates may uncover new such places that
+just happen to be non-problematic at the time of this patch.  If you are
+reading this due to finding such issues, feel free to contact me at
+elaexuotee@wilsonb.com for help.
