+Subject: [PATCH] Add a reproducibility option for building ecodes.c
+
+ecodes.c currently contains the kernel info of the build machine and the
+full path of the input*.h headers: This is not reproducible as output
+can change even is headers content do not. Downstream distributions
+might package ecodes.c and get non-reproducible output.
+
+To fix this: introduce a --reproducible option in the build:
+- in setup.py build_ecodes command
+- in underlying genecodes_c.py
+
+Note: These options are disabled by default so no change is expected in
+current builds.
