[src/trunk]: src/usr.bin/make make(1): rename struct For to struct ForLoop
details: https://anonhg.NetBSD.org/src/rev/c3da191c4a34
branches: trunk
changeset: 950349:c3da191c4a34

description:
make(1): rename struct For to struct ForLoop
This removes the ambiguity whether For_Free is meant to be a
module-exported function or a local function associate with that struct.
Rename the affected functions as well.
