Nothing more really? Not even a command-line like

frama-c -wp my_code.c

to run the WP plugin?

Going back to the original question: yes it seems that automatic provers
need a little help to establish the post-condition.

I attach the file I obtained after small modifications, and a dump of
the proof session obtained by the Jessie plugin. As you may see, you
need the Z3 prover to complete the proof.

Nice little exercise indeed,
