	I think reexamining the problem is A Good Idea.

	Let me propose that the structure turn into
	a loop which reads the line, expands any
	variables into a buffer and calls a back-end
	that doesn't have to parse anything. Then the
	same back end can use different front ends

	Perhaps the file parser might look like

	while (getline(line, size, fd) != EOF) {
		if ((name = getname(buffer) == NULL) {
			complain("no option, line);
		if (section_name(name)) {
			s = start_new_section(name);
		if ((value = parseval(p+2, buffer)) != NULL) {
			complain("no value", line);
		else if ((rc = add_option(s,name,value,errstr)) != 0) {
			switch (rc) {
			case 1: warning(errstr);
			case 2: error(errstr);
			case 3: horrible, can't continue

	A parser for something else could use the same add_option()
	and logic
