Yes.  Just as normal as if you created the file in a regular Windows
application; it will get the default ACL as defined by the standard NTFS
inheritance rules (parent directory, etc.)

Setup is not a Cygwin program, it is a native Windows program.  It does
not contain any of the "ntsec" logic needed to map POSIX modes onto
Windows ACLs.  It would be a lot of duplication to reimplement all of
this outside of Cygwin, and apparently it is not necessary.  This is
also why postinstall and preremove scripts run with the CYGWIN=nontsec
environment set, so that files created there have matching semantics.
