153 * 3) the type of operator used to define its sources (qv. parse.c)
154 * 4) whether it is involved in this invocation of make
155 * 5) whether the target has been remade
156 * 6) whether any of its children has been remade
157 * 7) the number of its children that are, as yet, unmade
158 * 8) its modification time
159 * 9) the modification time of its youngest child (qv. make.c)
160 * 10) a list of nodes for which this is a source (parents)
161 * 11) a list of nodes on which this depends (children)
162 * 12) a list of nodes that depend on this, as gleaned from the
163 * transformation rules (iParents)
164 * 13) a list of ancestor nodes, which includes parents, iParents,
165 * and recursive parents of parents
166 * 14) a list of nodes of the same name created by the :: operator
167 * 15) a list of nodes that must be made (if they're made) before
168 * this node can be, but that do not enter into the datedness of
169 * this node.
170 * 16) a list of nodes that must be made (if they're made) before
171 * this node or any child of this node can be, but that do not
172 * enter into the datedness of this node.
173 * 17) a list of nodes that must be made (if they're made) after
174 * this node is, but that do not depend on this node, in the
175 * normal sense.
176 * 18) a Lst of ``local'' variables that are specific to this target
177 * and this target only (qv. var.c [$@ $< $?, etc.])
178 * 19) a Lst of strings that are commands to be given to a shell
