Yes.  the patch convert all IPv4 mapped IPv6 address returned into
IPv4 address.  If someone announce mapped address using AAAA RR, it
also converted.  So, caller have no chance to know whether returned
address is mapped address or native IPv4 address.  However, I think
this is rare case in at least now.
After correcting getaddrinfo()'s search order, in some case, A RR is
accidentaly converted into mapped address without expectation of
caller.  This may confuse IPv4 people and force inconvenience.  I
worry about this.
Fixing ftp(1) and other caller is also important.  But, it is another
