Hi Lars,

AFAIR having the defsubst non native compiled is what we want as we need
the bytecode definition to have the inline to be performed.  Actually
the test is verifying that the defsubst is *not* native compiled.

I tried to reproduce here (0c993ed1d3) but for me the test is passing,
that's odd...

Thanks
