help with readlink

It reads symbolic links.  Symbolic links aren't available on (vanilla)
System III, so it can't be replaced.  Either the program you're working
on only works on systems with symbolic links, in which case you're out
of luck, or it does something like "stat"ing a file and if the file is
of type S_IFLNK does a "readlink" on it, in which case you can rip that
code out because 1) it won't compile on S3 because S_IFLNK isn't defined
and 2) that code won't get executed anyway because there won't *be* any
inodes of type S_IFLNK.
