The fix Matthias reffered to, is that you no longer need to pass -pthread explicitly if your program does not use pthreads. Please try it out -- it should not complain about pthread_cancel. As to -flto -- I can't say, but could you please provide self-contained testcase, preferably minimized, so we could try it out by ourselves too.
