Shoot.  The dd logic when [io]flag= omits both 'binary' or 'text' in 6.9-3 is:

[io]f= unspecified - no change to existing mode of std{in,out}
if= specified - default stdin to binary
of= specified - use mount point for stdout

There was a logic bug in my cygwin-specific patch for of= when I ported it from 
5.9x to 6.0 - in the process of accomodating upstream changes in the same 
section of the file, I accidentally swapped the order of some my lines, and the 
code that was supposed to default of= to binary became dead code.  Look for 
coreutils 6.9-4 coming soon to a mirror near you, with dd once again defaulting 
to full binary operation.
