custom stdc++

[Peter Skvarka]

I use cross compiler gcc 3.4.4 for arm9 target board.
I 'd like to adjust libstdc++.so so that some functions unused by our
embedded application will not be present.
Where can I found source code for libstdc++.co ?
I am seeing all stdc++ headers in my gcc 3.4.4 directory tree, but I dont
understand where to find sources for building
libstdc++.so.

Thank you !
Peter
