Comment(by ilyasokol@…):

 See these use cases:

 http://lists.boost.org/boost-users/2006/01/16620.php

 http://lists.boost.org/boost-users/2009/08/50968.php


 The signature can be changed as follows:

 {{{
 template<class charT>
 basic_parsed_options<typename remove_cv<charT>::type>
 parse_command_line(int argc, const charT* const argv[],
                    ....)

 or

 template<class charT>
 basic_parsed_options<typename remove_cv<charT>::type>
 parse_command_line(int argc, const charT* const* argv,
                    ....)
 }}}

 (The second is a bit more readable for me)

 There is no need to remove_cv<charT> and the change is fully
 backward compatible.
