I'm confused because the definitions of these functions are in the header include/std/fstream. I thought that inclusion of the header with the -std=c++0x flag would get the definition or that if PCH is used, at least one would have been compiled with -std=gnu++0x and provide the definition. I would have thought ODR would prevent having the definition here and in src/fstream-inst.cc. Or are you saying we should either: 1) move definition open(std::string) etc. to src/fstream-inst.cc (or maybe better src/fstream-inst_c++0x.cc to be consistent with other treatments). 2) move definition open(std::string) etc. to src/fstream-inst_c++0x.cc AND move definition open(const char *) etc. to src/fstream-inst.cc for consistency -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41005
