compiling errors with options "-fprofile-arcs -ftest-coverage"

Hi,
I need a help to compile my source files such that i can use gcov. When I 
tried to compile C files with the options "-fprofile-arcs-ftest-coverage", I 
got the error "undefined reference to `__gcov_merge_add'".

FYI : I am using gcc 4.1, SUSE 10.1

-Regards
