What about defining the code this way:
#ifdef AUTO_INC_DEC
+ static int
+ reg_inc_found_and_valid_p (unsigned int regno,
+                            unsigned int endregno,
+                            rtx insn)
+ {

...
}
#else

#define reg_inc_found_and_valid_p(regno,endregno,insn) 0

#endif

So you can remove ugly ATTRIBUTE_UNUSED.

Thanks,
