/* This is a chain of structures, each of which points at a Lisp_Object variable
 whose value should be marked in garbage collection.
 Normally every link of the chain is an automatic variable of a function,
 and its `val' points to some argument or local variable of the function.
 On exit to the function, the chain is set back to the value it had on entry.
 This way, no link remains in the chain when the stack frame containing the link disappears.

 Every function that can call Feval must protect in this fashion all
 Lisp_Object variables whose contents will be used again. */
