80a0e9b5f5 Allow creating hard links to symlinks using ln(1). 
This implements the POSIX.1-2008 -L and -P flags.

The default remains to create hard links to the target of symlinks.

d605a06c6e Unbreak last commit to ln for amd64. 
Cast string precision to `int'.  amd64 systems warn about the
field precision being `long int' if we don't, and pathnames are
normally short enough to fit in an `int'.

3595f21aae Add a -w warning flag to ln(1). When the -w option is enabled, 
ln(1) checks to see if the source of a symlink, i.e. the file it
should point to actually exists.  The default is the old ln
behavior, that does not check, to avoid surprising people who may
be using ln(1) in scripts or other non-interactive places.
