/*	To determine the minimum scope of a local variable, all (braced)
	scopes are numbered consecutively.  Next we maintain an array which
	maps the nesting depth (level) onto the scope number; we record
	the scope number of the first application of a local variable
	in its definition.  Each further application requires that the
	level of the variable be at least large enough to comprise both
	the present scope and that of its first application.  That level
	number is determined by searching the array and is then recorded in
	the definition (beacuse it is always equal to or smaller than the
	level already there).

	The array is implemented as a linked list of struct brace.
