     Type:  Bugs                     |      Status:  new          
Milestone:  Boost 1.44.0             |   Component:  format       
  Version:  Boost Development Trunk  |    Severity:  Cosmetic     
 Keywords:  format C2442             |  
-------------------------------------+--------------------------------------
 Creates a blizzard of C2442 warnings when called from Boost.Test.

 I:\boost_1_43_0\boost/format/alt_sstream.hpp(128): warning C4224:
 nonstandard extension used : formal parameter 'arg' was previously defined
 as a type
           I:\boost_1_43_0\boost/format/alt_sstream.hpp(145) : see
 reference to class template instantiation
 'boost::io::basic_oaltstringstream<Ch,Tr,Alloc>::No_Op' being compiled
           with
           [
               Ch=char,
               Tr=std::char_traits<char>,
               Alloc=std::allocator<char>
           ]

 Problem is in class basic_oaltstringstream

 template<class T>
                 const T & operator()(const T & arg) { return arg; }

 This trivial change of name from "arg" to "arg1" cures it.

 template<class T> const T & operator()(const T & arg1) { return arg1; }
