I've got my patch ready but need to test it before submitting it.  In the 
meantime, I just noticed that all of the directories you've listed have 
non-standard ACL entries (indicated by the + signs).  getfacl should show you 
what they are.

Cygwin does not do this on a standard installation.  Is it something you've done 
intentionally?  If not, you might want to remove those non-standard entries and 
see if that has any impact on the problems you've reported.  The -b and -k 
options to setfacl are useful here.
