00003  * gcc sometimes likes to insert implicit calls to memcpy().
00004  * Unfortunately, there doesn't seem to be any way to prevent it from
00005  * doing this, or to force it to use the optimised memcpy() as seen by
00006  * C code; it insists on inserting a symbol reference to "memcpy".  We
00007  * therefore include wrapper functions just to keep gcc happy.
