You could just do a

	struct entry list[10]; 

and not use pointers at all.  Or, if you really need to use pointers you
could do:

	#define CNT 10

	struct entry *list[CNT];
	struct entry  reallist[CNT];

and somewhere in the begining of your program do:

	for(i=0; i < CNT; i++) list[i] = reallist+i;
