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