[rdiff-backup-users] Building rdiff-backup on Windows

[Josh Nisly]

I now have rdiff-backup building and performing local backups and 
restores. This includes the initial backup, as well as subsequent 
backups with changed files. I'm working on using Plink to back up to a 
remote server, but I'd like to start submitting patches for my work so 
far. I'd really like to get these into the main tree, so if there are 
any problems with them, please let me know and I'll try to fix them.

The first patch is for rdiff-backup's cmodule.c. Since lstat is not 
available on Windows, it uses _stati64, which Microsoft's replacement. 
It also replaces sync with _flushall(), which is documented to 
accomplish the same thing: 
http://msdn2.microsoft.com/en-us/library/s9xk9ehd(VS.71).aspx.

The second patch is two simple changes to setup.py to build the main 
package. It allows building with rsync.lib in the source folder. The 
second change tells the linker not to link in libcmt.lib.

Could someone with commit access please review these patches?

Thanks,
Josh Nisly
