It doesn't notice that the functions are referenced and doesn't compile them in. You can work around it by decreasing the optimization level when compiling main.cc (the default -O3 includes -finline-functions, which is the culprit). I have already reported that bug to bug-g++, hopefully it will be fixed in the next release. Andreas.
