Hi Bob,

I wasn't able to find any documentation on Cygwin extensions to deal
with ACLs - did you have a particular utility in mind for this? 

I would expect that the normal behavior of cp would be as you said that
it would not preserve permissions, and thus the new files in this 
subdirectory would be assigned the inherited ACLs - correct? This didn't
occur when using Cygwin's "cp", so it seems that some additional action
is occurring which either overrides or occurs after the inherited ACLs
are set.

Thanks,

Andrew
