Fixed compile error on FreeBSD 9.

I have the same issue patched in my preliminary port directory. I have used the solution chosen by the author of the databases/leveldb port:

On a similar matter, have you had a look at the bitcoin FreeBSD port? I'd like to get some input from the bitcoin community. There are bound to be some "but we do it this way" issues to compromise on, of course, but all comments are welcome.

All I did was replace the port_posix.h file in bitcoin with the one from the latest commit of leveldb. It seems to me like the cleanest option.

[luke-jr]

Note the bitcoin codebase doesn't work in big endian at all right now. Also note that despite many headers/software making the assumption that endian is fixed at build time, that assumption is apparently not necessarily true in theory.

The cleanest option is to use a git submodule to embed LevelDB, at least until it's possible to build/link with system LevelDB.

Well, if anything, upgrading to a newer upstream version of the the port_posix.h file is no problem in my opinion, certainly if it fixes building for some people.

Automatic sanity-testing: PASSED, see http://jenkins.bluematt.me/pull-tester/17bfb1f4378445aaf5b3c3afdd47e289e22c0545 for binaries and test log.

[sipa]

Alternatively, we could try updating to LevelDB 1.6 entirely?

[Diapolo]

@sipa Is there a changelog fot that available? IMHO as long as there is no stable release available, we are free to do this whenever it's needed / wanted :).
