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.

case1
[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 );
            if( p->cpu & X264_CPU_SSSE3 )
                p->cpu |= X264_CPU_SSE2_IS_FAST;
            if( p->cpu & X264_CPU_SSE4 )
                p->cpu |= X264_CPU_SHUFFLE_IS_FAST;
        }
    }
[/code]

case2
[code]
    while( (tok = strtok_r( p, ",", &saveptr )) )
    {
        char *val = strchr( tok, '=' );
        if( val )
        {
            *val = '\0';
            val++;
        }
        if( x264_param_parse( z->param, tok, val ) )
        {
            x264_log( h, X264_LOG_ERROR, "invalid zone param: %s = %s
\n", tok, val );
            return -1;
        }
        p = NULL;
    }
