bash's behaviour is still a but surprising IMHO. While globstar doesn't
descend further into symlinks, symlinked directories are selected as a
candidate for matches to ** itself. But zsh doesn't do this:

wooledg:/tmp/x$ mkdir dir; ln -s dir link; touch dir/file
wooledg:/tmp/x$ shopt -s globstar
wooledg:/tmp/x$ echo **
dir dir/file link
wooledg:/tmp/x$ echo **/file
dir/file link/file

I think the complaint is about the handling of "**/file" here.

Yep, that's an incompatibility. The `c.c' thing in the original report is
just a red herring, though.

So, given

|-- dir
|   +-- link -> ../otherdir
+-- otherdir
    +-- subdir
        +-- foo

(that is: mkdir -p dir otherdir/subdir; ln -s ../otherdir dir/link; touch otherdir/subdir/foo )

dir/**/foo does not match anything, but dir/**/subdir matches dir/link/subdir , i.e. ** looks through the link, but doesn't recurse through it? Did I get that right?

That does seem somewhat surprising. The documentation on globstar doesn't seem to mention anything about behaviour re. symlinks either.
