[rdiff-backup-users] cygwin fsyncing again

[Dave Kempe]

Hi,
I am trying to get rdiff-backup 1.0.1 going on cygwin. I will have a 
windows package built shortly, but I would love it if windows-> windows 
backups worked.
the initial backup works ok, but after the session stats are printed at 
the end I get an error similar to the one below. Thats fine, but 
subsequent backups crash with the error below before copying any files. 
I think os.fsync is not available on cygwin python2.4 and is erroneously 
turned on...

Let me know if there any other information you need to help me out - is 
there some way I can turn off fsyncing on cygwin?

thanks

dave

Previous backup seems to have failed, regressing destination now.
