Hash: SHA1
According to Jim Meyering on 6/6/2009 2:41 PM:
> A few of the function declarations in hash.h could benefit from

Including one in hash.c itself:
hash.c: In function `hash_delete':
hash.c:1015: warning: ignoring return value of `hash_rehash', declared
with attribute warn_unused_result
We should fix this, and decide whether shrinking the hash table when
deletion frees up a bucket is always possible, or else deal with memory
allocation failure here, too.
