OK, but
char *strtok(char *_s1, const char *_s2);
has only 2 arguments. The 3rd argument is described:
s3 is a value-return parameter used by strtok_r() to record its
progress through s1.

I'm not sure if I could safely delete s3 in function call.

[code]
    OPT("asm")
    {
        p->cpu = isdigit(value[0]) ? atoi(value) :
                 !strcmp(value, "auto") || atobool(value) ?
x264_cpu_detect() : 0;
        if( b_error )
        {
            char *buf = strdup(value);
            char *tok, UNUSED *saveptr=NULL, *init;
            b_error = 0;
            p->cpu = 0;
            for( init=buf; (tok=strtok_r(init, ",", &saveptr));
init=NULL )
            {
                for( i=0; x264_cpu_names[i].flags && strcasecmp(tok,
x264_cpu_names[i].name); i++ );
                p->cpu |= x264_cpu_names[i].flags;
                if( !x264_cpu_names[i].flags )
                    b_error = 1;
            }
            free( buf );
