I fixed it with less changes by:

diff --git a/include/string.h b/include/string.h
index 8323412..c9bee10 100644
--- a/include/string.h
+++ b/include/string.h
@@ -1,5 +1,7 @@
 #ifndef _STRING_H
 
+#define _STRING_ARCH_unaligned 0
+
 #ifndef _ISOMAC
 #include <sys/types.h>
 
It will also shows for arch that this flags can be set if arch supports it.
