From bfaa02d8a9aad6c31523329053c615c69ef2c185 Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@cs.ucla.edu>
Date: Mon, 2 Aug 2004 23:36:33 +0000
Subject: (have_read_stdin, append_quoted, dc_parse_stream, dc_parse_file,
 main): Use bool for booleans. (dc_parse_stream): Use enum for state, rather
 than int. Use ssize_t to store getline result.
