No, it hasn't. For some ACLs, see below.

I looked up what these two mean and in fact it sounds like the problem; 
I had previously sent the output of getfacl on the drive directories and 
on directories manually created there, don't know if that helps:

Also, speaking of ACLs and pondering about possible effects of their 
inheritance, it comes to my mind that it might make a difference whether 
to create H:\cygwin in a mounted H: drive or H:\mydir\cygwin so I'll try 
that next time.

Great, so I'll wait.
Concerning "time until release", if you want me to test something 
tomorrow morning that's OK, if you want me to test something today, 
please provide compiled debug versions somewhere on the net as I cannot 
compile it here.
