There's a new problem: In the same code

	security.cc: set_process_privileges()

the call to AdjustTokenPrivileges() behave different:

On setting SE_RESTORE_NAME and SE_BACKUP_NAME rights, GetLastError()
returns
	ERROR_SUCCESS in winsup-990303 and
	ERROR_NOT_ALL_ASSIGNED in winsup-990430.
As a result, it's impossible for admins, to chown to another user in
winsup-990430 :-(

Is anybody willing to help?
