[ 2010-11-03 Daniel comments and suggests alternative wording: ]

The proposed resolution needs to use basic_string<charT> instead of basic_string<char>

Previous Proposed Resolution:

Make the following changes to [re.regex.assign]:

basic_regex& assign(const charT* ptr, flag_type f = regex_constants::ECMAScript);

12 Returns: assign(string_typebasic_string<charT>(ptr), f).

basic_regex& assign(const charT* ptr, size_t len,
  flag_type f = regex_constants::ECMAScript);

13 Returns: assign(string_typebasic_string<charT>(ptr, len), f).

[..]

template <class InputIterator> 
  basic_regex& assign(InputIterator first, InputIterator last, 
                          flag_type f = regex_constants::ECMAScript);

18 Requires: The type InputIterator shall satisfy the requirements for an Input Iterator (24.2.3).

19 Returns: assign(string_typebasic_string<charT>(first, last), f).
