So as a lowly maintainer of an unsupported GCC port I ask: what is problem
in just  modifying my-port's C library headers like so:

void* 	memcpy (void*, const void*, size_t);
#if defined __GNUG__  && !defined __STRICT_ANSI__
extern inline memcpy (void* _S1, const void* _S2, size_t _N)
  {  __builtin_memcpy(_S1, _S2, _N) ; }
#endif


other than the problem of un-builtin-izing if user defines own
implementation of memcpy
