> find -L . -type l prints a list of symbolic links reachable from the current directory that do not resolve to accessible files.


Hmm. I never considered this before, but does the use of "accessible" here imply that EACCES should also count?

Reading the specification again:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/find.html

This means that an error should not be thrown for broken links (well, probably
only for primitives that require the symlink to be resolved like '-printf %Y').

And later on:

The spec does not differentiate between ENOENT and ENOTDIR here.
So the current behavior seems to be debatable, at least.
I have to think about this ...

$ touch file
$ ln -s nowhere broken
$ ln -s file/nowhere notdir
$ find -L
.
./file
./broken
find: ‘./notdir’: Not a directory
./notdir

So we get an error message if a link is broken in one way but not another. Worse,

$ find -L broken
broken
$ find -L notdir
find: ‘notdir’: Not a directory

So at the top level, notdir is not even printed. Same with -H.
