버전에 따른 문제점

아래의 프로그램이 red hat 9에서는

$ gcc -O2 time-timers.cpp -o time-timers
$ ./time-timers

으로 정상적으로 실행되지만, 동일한 명령

$ gcc -O2 time-timers.cpp -o time-timers

을 Fedora Core 3에서 실행하면

/tmp/ccduuohe.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status

처럼 오류가 납니다. 뭘 고쳐주면 될까요?
