[src/trunk]: src/usr.bin/make make(1): rename Stack to Vector
details: https://anonhg.NetBSD.org/src/rev/5e45da7a3299
branches: trunk
changeset: 1015223:5e45da7a3299

description:
make(1): rename Stack to Vector
Both Var_Dump and GetActuallyIncludingFile access more than only the top
item of the stack, therefore it is more honest to rename the data type.
