rsync 3.0.5 Appears to be Transferring Unchanged Files

Further testing has determined that the rsync command is working as 
advertised.  backuppc uses a Perl implementation of File::RsyncP that 
communicates with rsync.  The Ubuntu port for ARM processors appears to 
label a significant number of blocks as changed even through the source 
and target files are identical.  The problem has been reported to Craig 
Barratt and the ubuntu-devel-discuss mailing list.
