Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
ros-genpy generates unreproducible Python code output. This is
currently affecting at least three source packages in Debian unstable.
Patch attached that ensures that the "struct" code stanzas are
emitted in a deterministic order.
