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