/**
   * Set the _options map based on the current project/workspace settings. There is a bug in Sun's
   * apt implementation: it parses the command line incorrectly, such that -Akey=value gets added to
   * the options map as key "-Akey=value" and value "". In order to support processors written to
   * run on Sun's apt as well as processors written without this bug in mind, we populate the map
   * with two copies of every option, one the expected way ("key" / "value") and the other the Sun
   * way ("-Akey=value" / ""). We make exceptions for the non-dash-A options that we set
   * automatically, such as -classpath, -target, and so forth; since these wouldn't have come from a
   * -A option we don't construct a -Akey=value variant.
   *
   * <p>Called from constructor. A new Env is constructed for each build pass, so this will always
   * be up to date with the latest settings.
