[uClibc-cvs] uClibc/libc/inet resolv.c,1.42,1.43

[Erik Andersen]

Update of /var/cvs/uClibc/libc/inet
In directory winder:/tmp/cvs-serv7258

Modified Files:
	resolv.c 
Log Message:
Patch from Jay Kulpinski:
    __decode_dotted() does not count the null terminating byte of
    a hostname in the DNS response.  This causes lookups to fail
    if the DNS response doesn't compress domain names in the
    message.
