Also like I said, ~/sun also works perfectly fine in /cygdrive/g/cygwin/ but
not if I created a subdirectory with the shell's mkdir command.
Can you give us more information about where that error is coming from? Are you

Thanks. The problem is that fhandler_base::acl_get *always* returns ENOTSUP. I
think we need a method fhandler_socket_local::acl_get that calls
fhandler_disk_file::acl_get on the underlying socket file when it should.
(There's already a similar method, fhandler_socket_local::facl.) I'll submit a
patch to do that, and then getfacl should work on socket files. I'm not sure
what further work will be needed to deal with the problems you reported, but
that's a first step.
