Notes on the --with-resolv configuration option:

On systems which use YP/NIS, you may still prefer to link with -lresolv
(assuming it's present), which causes the ftp client to query the DNS
directly when resolving hostnames.  The sole advantage to this is that you
can use aliases for host names as defined in the file specified by your
HOSTALIASES environment variable.  The main disadvantage is that you will
be unable to resolve local hostname that are defined in NIS maps but not in
the DNS.  Personally, I tend to care more about having HOSTALIASES support,
but your mileage may vary.

On Solaris2 platforms, it is necessary to use the function
`res_gethostbyname' instead of `gethostbyname' in order to get the version
of the resolver function which consults your hostaliases file.  The
configure script automatically uses that function if it's found (which only
happens if you link with -lresolv).

By default, this package does not attempt to link with -lresolv.
