Compiling error of hping: “DBYTE_ORDER_(BIG|LITTLE)_ENDIAN”

Taken from the original post.
Symptom:

[root@localhost hping3]#./configure

bytesex.h:22:3: error: #error can not find the byte order for this architecture, fix bytesex.h

In file included from rapd.c:11:
 ars.h:190:2: error: #error "Please, edit Makefile and add -DBYTE_ORDER_(BIG|LITTLE)_ENDIAN"
 ars.h:254:2: error: #error "Please, edit Makefile and add -DBYTE_ORDER_(BIG|LITTLE)_ENDIAN"

 now you can try `make'

To resolve:

Since this was a x86_64 architecture, and it was not in the bytesex.h you just need to add in a line as below  and ./configure again.
[root@localhost hping3-20051105]# cat bytesex.h
