I've noticed that
plain pdfTeX (without texinfo) can generate PDF destination names
and web browsers can jump to them.

If I understand correctly,
Ghostscript seems to discard PDF destination names.

I've reported to Ghostscript Bugzilla.

Yes.

If you use `ps2pdf foo.pdf foo.new.pdf`,
foo.new.pdf contains PDF outline but PDF viewers do not show it in default.
In this case, you can show it by some operating the PDF viewer.

On the other hand,
if you use the command I showed instead of `ps2pdf`,
PDF viewers show the PDF outline in default.

What exactly do you mean with `hidden'?  Are PDF viewers still capable
to show the outlines?

Hmm.  This smells fishy.

I was wrong.

PDF outline is not lost.
It is hidden.
The following command can let show it.

$ gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=foo.new.pdf foo.pdf -c 
'[ /PageMode /UseOutlines /DOCVIEW pdfmark'

For remote PDF links, rather than they are lost,
I think that PDF destination names are replaced.

Would you know a tool other than texinfo
that can generate remote PDF links?

Interesting.  Do you think this is a bug in gs or in texinfo, or both?
And do you have time to send bug reports and/or asking for help?

I've tried Ghostscript 9.19.
The following warnings are displayed a lot.

    Warning: Outline has invalid link that was discarded.
    Warning: Link annotation points out of the document page range.

I think this is due to texinfo.tex bug.
This patch might fix it.

```

However, even if fix this, there are two problems.

PDF outline is lost.
Remote PDF links (between PDFs) are lost.
