See the thread related to
http://gcc.gnu.org/ml/gcc-patches/2005-05/msg02424.html .
The problem is that the new builtin atomic functionality does not support all of
the special cases that the inlined assembly supported. libstdc++ now is using
builtins. Paolo apparently cannot fix the breakage that he caused and is
dropping the problem on the port maintainers.
