Ok, I just sent a patch. It's entirely untested, but it compiles, so
it must be perfect.
People should double-check that the headers (for memcpy and for the
htonl() stuff) are sufficient for OSX and Windows, but the code itself
is what git uses, so it shouldn't really have any real portability
gotchas. But our header files are a bit different from the git ones,
as is obviously our build environment, so it's possible that there is
some "Windows needs xyz.h in order to use <arpa/inet.h>". I wrote the
git code, but others handled the Windows oddities.
