Тип бы надо всё таки привести раз функция так описана

Ну а вообще на мой взгляд было бы кошернее
static Options cmd[] = {
{"squidlog", "access.log"}, // path to squid access.log file
{"config", "trafficd.conf"} , // path to trafficd conf file
};
// на момент компиляции размер масива cmd уже известен
// Посчитаем число элементов
#define MAX_INDEX = (sizeof(cmd)/sizeof(struct Options));
struct Options *OptionGetVal(Options *opt, char *name) {
int i=0;
while ( i < MAX_INDEX ){
if (!strcmp(name,opt[i].name))
return(opt[i]);
i++;
}
return NULL;
}
И соответвено:
printf("squidlog=%s\n", (char *)OptionGetVal(cmd,"squidlog")->val);
