Page 147: The closing parenthesis of the for-loop is missing.
On page 149, Listing 16.1, the include-guards are defined as H_LINKED_LISTS_H. However, the name of the header file is linked-list.h, without an “s”, therefore the include-guards should be H_LINKED_LIST_H.
Page 155, in cmp2() we have
```
struct point *a = (struct point *)aa;
```
That's not wrong, but the cast is redundant since the void pointer is compatible with all pointer types. That line may be written simply as
```
const struct point *a = *aa;
```
The redundant casts in the next two lines may be removed in the same way.
Page 158: The line
```
int catch_the_odds(void *aa)
```
should be
```
int catch_the_odds(const void *aa)
```
to be consistent with the declaration of ll_filter().

On page 160, Part 16.3, the line

conscell *ll_append(cons struct *list1, cons struct list2);

is totally botched. It should be

conscell *ll_append(conscell *list1, conscell *list2);
