Hi, Clement Another, optional object file in libgcc seems like a cleaner solution than collect2.c emitting all of the code. The file should not be called crtcxa_cdtors.o because "cxa" came from the name of the libstdc++ support functions. Maybe crtcdtors.o or crt_cdtors.o or aixcdtors.o or aix_cdtors.o . Thanks, David
