pademelon doesn't.

Also, I think there are some other non-gcc animals that nominally allow
"static inline" but will generate warnings when such functions are
unreferenced in a particular compile (that's what the "quiet inline"
configure test is about).  That would be hugely annoying for development,
though maybe we don't care too much if it's only a build target.

I'm not against requiring static inline; it would be a huge improvement
really.  But we should not fool ourselves that this comes at zero
compatibility cost.

Of these I think only the first is really worth breaking portability
for.
