	* builtins.c (expand_builtin_sprintf): Use c_getstr and strlen to
	obtain the format string instead of using TREE_STRING_POINTER and
	TREE_STRING_LENGTH.  Only optimize sprintf(dst,"%s",src) when the
	return value is unused or the length of src is a known constant.

	* gcc.c-torture/execute/string-opt-16.c: Remove test for disabled
	sprintf(dst,"%s",src) optimization.
	* gcc.c-torture/execute/20030626-1.c: New test case.
