Build issue on DragonFly BSD (patch to build correctly included)

[cmumford]

Original issue 192 created by admin@garyshood.com on 2013-07-21T23:59:36.000Z:

What steps will reproduce the problem?

1. Compile leveldb on DragonFly BSD
2. Error output the same as https://code.google.com/p/leveldb/issues/detail?id=98

What is the expected output? What do you see instead?
Expected output is compilation, actual output is

In file included from ./port/port.h:14,
from ./db/filename.h:14,
from db/builder.cc:7:
./port/port_posix.h:67: error: '__BYTE_ORDER' was not declared in this scope
./port/port_posix.h:67: error: '__LITTLE_ENDIAN' was not declared in this scope

What version of the product are you using? On what operating system?
leveldb-1.12.0 on DragonFly BSD 3.2.4

Please provide any additional information below.
I have attached a patch that fixes this. The same exception made for FreeBSD just has to be made for DragonFly BSD as well.
