Re: [rdiff-backup-users] Winows - large files and binary edits with no date change

[Josh Nisly]

I don't know about the first problem (I though rdiff-backup on linux 
handles it.) The second problem is because one of the underlying 
libraries has a bug dealing with large (>4GB) files. There is a patch 
available that is typically applied on linux, but when I wrote the build 
script, I simply failed to include it. I'll try to change this soon.

Thanks,
