 * 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.
