Detailed Description

gcc sometimes likes to insert implicit calls to memcpy() and memset().

Unfortunately, there doesn't seem to be any way to prevent it from doing this, or to force it to use the optimised versions as seen by C code; it insists on inserting symbol references to "memcpy" and "memset". We therefore include wrapper functions just to keep gcc happy.
