Actually, on a second read through the documentation,
gsl_set_error_handler_off() should do what you want.  Surround your
call with something like the following:

gsl_set_error_handler_off();
result = gsl_root_fdfsolver_newton(...);
gsl_set_error_handler(NULL);

and then check result against the standard GSL error codes.
