--- Comment #34 from David Edelsohn <dje at gcc dot gnu.org> 2011-11-05 15:51:54 UTC --- I am trying to bootstrap with --disable-multilib to at least be able to build GCC while we try to fix this. Adding the braces removes the first error, but In file included from /farm/dje/src/src/libstdc++-v3/src/atomic.cc:28:0: /tmp/20111104/powerpc-ibm-aix5.3.0.0/pthread/libstdc++-v3/include/mutex: In function 'void std::call_once(std::once_flag&, _Callable&&, _Args&& ...)': /tmp/20111104/powerpc-ibm-aix5.3.0.0/pthread/libstdc++-v3/include/mutex:818:64: error: invalid conversion from 'void (*)(...)' to 'void (*)()' [-fpermissive] remains. Thanks! David
