commit ac406d38e49d4bbe2c6b41680abf7c717ce9b393

    ntbtls-cli: Use union to access hostent addr.
    
    * src/ntbtls-cli.c (connect_server): Use union.
    
    --
    
    Unfortunately, the API of gethostbyname was designed in old style of
    C.  Modern compiler emits warnings for its access to h_addr of char *
    on a machine of different alignment requirement for other
    objects.  (It should be defined as void *, in new style.)
    
    As a workaround, we use union here.
