Permissions on Files Created with Cygwin

[Rob Stevens]

Whenever I create files with cygwin (using whatever utilitity or editor)
I get these permissions as reported by icacls:
   NULL SID:(DENY)(Rc,S,X,DC)
   MALIN\rob:(R,W,D,WDAC,WO)
   NT AUTHORITY\SYSTEM:(DENY)(S,X)
   BUILTIN\Administrators:(DENY)(S,X)
   MALIN\None:(R)
   NT AUTHORITY\SYSTEM:(RX,W)
   BUILTIN\Administrators:(RX,W)
   Everyone:(R)
These permissions are not those inherited from the containing directory.
Not that only, but the windows utilities complain the the
permissions are mal-ordered.

Is this not a bug?? Do I need a different (null?) umask in the environment?
