Where did this information come from? The *only* thing "memory.h" is
for is memcpy, memset, etc. which belong in string.h and have always
been in string.h. The whole "memory.h" thing was some BSD nonsense,
probably because they preferred their bzero, bcopy, etc. interfaces
and were bitter than mem* was adopted by ANSI/ISO C.
