Hi,

  The trivial patch below fixes a bogus testsuite failure
  (gcc.dg/pr78138.c) for the avr target.

  The declaration for memcpy had the size parameter declared as 
  unsigned long. For avr, __SIZE_TYPE__ is unsigned int, and 
  this caused a builtin-declaration-mismatch warning, resulting
  in a couple of FAILs.

  The patch fixes that by typedef'ing __SIZE_TYPE__ to size_t and
  using size_t as the type for memcpy's third parameter.

  Committed to trunk as obvious.

Regards
Senthil

	unsigned long.
