+ level. Those optimizations are not always a good idea since this
+ means the code size increases a lot. Instead the definitions here
+ optimize some functions in a way which do not dramatically
+ increase the code size and which do not use assembler. The main
+ trick is to use GCC's `__builtin_constant_p' function.
+
+ Every function XXX which has a defined version in
+ <bits/string.h> must be accompanied by a symbol _HAVE_STRING_ARCH_XXX
+ to make sure we don't get redefinitions.
+
+ We must use here macros instead of inline functions since the
