   3  * gcc sometimes likes to insert implicit calls to memcpy() and
   4  * memset().  Unfortunately, there doesn't seem to be any way to
   5  * prevent it from doing this, or to force it to use the optimised
   6  * versions as seen by C code; it insists on inserting symbol
   7  * references to "memcpy" and "memset".  We therefore include wrapper
   8  * functions just to keep gcc happy.
