memcpy is in the cstring header file, and is therefore in the std
namespace on any modern/conforming compiler.

Box is including a lot of deprecated header files which are often marked
as such on newer compilers. We should fix all of them really.

Any old ISO C 89 header such as <string.h> loses the .h and gains a
leading c, ie. <cstring>, <cstdio>, <cctype>, <cstdlib>, etc. All
contents are in the std namespace.

POSIX header files such as <unistd.h> are unaffected. I'm sure there's a
list somewhere out there.

Cheers,
Martin
