libstdc++ developing

[Marek Zuk <marekzuk at gmail dot com>]

Hi,

I'm in my final year of my studies(MSc) at the Faculty of Mathematics & 
Computer Science at the Warsaw University of Technology and I'm working 
on  my final project.
In my project I'm going to develop libstdc++. The the subject of my 
project is: "Enhancing associative containers (map, multimap, set and 
multiset) in STL with the possibility of choosing the way of their 
implmentation".

Now associative containers in STL are implemented by use of red-black 
trees. What I want to do, is to enable the choice of implementation of 
these containers by adding one parameter to the templates, so that the 
containers could by be built by use of  b-trees, just vectors or others 
structures.

I'm relatively new to the compiling process of GCC, so I have questions:
1. How to make changes in libstdc++ and how to test these changes in the 
easiest way?
Yesterday I sent a similar e-mail to gcc-help list, but I didn't get a 
satisfying answer, so I'm asking once again.

2. Is it possible to apply my changes to libstdc++, if they are 
succesful? What is the process of applying such changes to the GNU C++ 
standard library? Who could I consult with about my ideas of development 
the libstdc++?

Thanks in advance
