Yup, GNAT expects certain functions to be present and generates calls to
them. Check system.ads for mention of allowing assignment, that basically
calls memcpy on assignment for objects that require a memory copy rather
than a register to register copy.

Others are bzero/ memset.

No idea, never used them.
