I'll change the setup script to handle the --librsync-dir option for 
both posix and nt. Windows doesn't have the neat include and lib 
folders, so it makes it a little bit more of a pain to build, but I 
think that's ok, since Windows is very much a secondary platform.

I've got a script I use that downloads and builds librsync, checks out 
rdiff-backup, patches, and builds it (this is harder on windows than on 
linux! :-). I'll post this script once things get a little closer to 
completion.

Did you mean necessary or unncecessary? Since I'm scripting it, I can 
handle it either way, but including it will make it easier for others to 
build.
