I had always just assumed that -Wstrict-prototypes was part of -Wall,
but it is not (nor even part of -Wextra!). Maybe it is time to add it to

Looks like we also need this on top of hv/submodule-config (still in pu,
so squashing is probably best):

diff --git a/submodule-config.h b/submodule-config.h
