1. No wonder as it says "// Low-level functions for atomic operations:
x86, x >= 4 version". 
gnu/gcc-3.22/libstdc++-v3/config/cpu/i386/bits/atomicity.h should be
used, not gnu/gcc-3.22/libstdc++-v3/config/cpu/i486/bits/atomicity.h
(which says "atomic operations: x86, x < 4 version").

2. It won't help as xaddl is present in that one too. Nevertheless the
i486 version will most likely never do the right thing for i386.

3. Meanwhile what's wrong with
gnu/gcc-3.22/libstdc++-v3/config/cpu/generic/bits/atomicity.h?


Right,
