That is, one commit added extern keywords, so that the next commit could
use the presence of extern keywords to check whether scoping policy is
being properly followed.
It doesn't help or hurt C to have the explicit extern, other than having
the explicit extern makes source code easier to pass through perl to
validate whether non-static declarations were intentionally meant to be
externally visible, rather than accidentally missing 'static'.
