[v3]libstdc++/13631

[François Dumont <francois dot cppdevs at free dot fr>]

Hello

    I have started working on 13631. I finally didn't use code posted 
on bugzilla, it is a patch for some rather old code. For the moment I 
have attached what I have done and here under is one of the errors that 
appear as soon as I introduce the map.

/home/fdt/dev/gcc-build/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so: 
undefined reference to `std::_Rb_tree<int, std::pair<int const, 
std::basic_string<char, std::char_traits<char>, std::allocator<char> > 
>, std::_Select1st<std::pair<int const, std::basic_string<char, 
std::char_traits<char>, std::allocator<char> > > >, std::less<int>, 
std::allocator<std::pair<int const, std::basic_string<char, std::char
_traits<char>, std::allocator<char> > > > 
>::_M_insert_unique(std::pair<int const, std::basic_string<char, 
std::char_traits<char>, std::allocator<char> > > const&)'
collect2: ld returned 1 exit status
compiler exited with status 1

    It looks for some missing symbols. What should I do ? Export the 
necessary std::map instanciation from the lib ? Avoid usage of std::map 
and use some hand written data structure ?

Thanks for any help
