patch from Jari Korva <jpkorva@iki.fi>:
- fixes endianness bug in gethostbyaddr() (i386 worked fine, while m68k didn't: 192.168.160.162 was queried with 192.168.160.162.in-addr.arpa while it should have been 162.160.168.192.ip-addr.arpa) - contains missing pieces from my previous getnameinfo() patch: now it actually compiles!
