* lib/cgi.rb (CGI::QueryExtension::Value::[]): should work like

  String#[] if more than one arguments are specified.

* lib/delegate.rb: avoid using common instance name as "@obj".

* lib/cgi.rb (CGI::QueryExtension::Value): Value is no longer
  subclass of String, but DelegateClass(String).

* ext/curses/extconf.rb: restore function check for init_color.
  [ruby-list:38905]

* Makefile.in: need to specify $(MAINLIBS) for the miniruby
  generation rule.

* configure.in: better FreeBSD -lc_r support.
