This is your problem: that binutils chokes on this file. This is the
correct atomicity file for your setup (x86_64).

%ld --version
GNU ld version 2.14.90 20031208

Au contraire: atomicity.h is used all over the place, including when libstdc++ is built. 

%grep atomicity *
ios.cc:#include <bits/atomicity.h>
ios_init.cc:#include <bits/atomicity.h>
locale.cc:#include <bits/atomicity.h>
locale_init.cc:#include <bits/atomicity.h>
misc-inst.cc:#include <bits/atomicity.h>

Also, all std::string.

There's something else wrong.

ps. When I get bug reports from people that can use bitkeeper and have
licenses to Perennial C++ I get a bit weepy, so sorry if this is too harsh.
