To clarify what's going on here. We confess in our doc (
http://www.gpsbabel.org/htmldoc-development/fmt_kml.html ) that KML can express all kinds of stuff that GPSBabel (indeed, many KML readers) simply can't consume. For example if you look at your first file in its entirety, you'll see that it contains:
$ cat Chinchorrospr.kml
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="
http://www.opengis.net/kml/2.2" xmlns:gx="
http://www.google.com/kml/ext/2.2" xmlns:kml="
http://www.opengis.net/kml/2.2" xmlns:atom="
http://www.w3.org/2005/Atom">
<NetworkLink>
<name>Chinchorrospr</name>

</Link>
</NetworkLink>
</kml>
Even if angle brackets make your head hurt, you can see that it doesn't contain "scores of waypoints"; it contains a Network link that, when fetched over the network, resolves to a KML file that contains scores of points.
GPSBabel really can't handle the task of fetching network links like that. If you do it manually and save that resulting KML to a file (as Phil suggested) you get a file we can successfully read; we see 350 points in that file.
Long ago, I started a project to integrate
libkml that would help with things like that, recursive style resolution, and many other "KML-isms" that are just plain difficult. While it offered a lot of interesting features, the combination of C++ and code size (both of which I'm pretty much over) and other distractions meant that I never really finished it and integrated it.
So for now, you have to manually untangle Network links and do the fetch yourself before feeding them to GPSBabel.

Thanks for the responses everyone!
Khai - you said my kml file is "essentially empty". I grant you that it may use some kind of network indirection, but there are in fact scores of waypoints visible when I reload the link I attached yesterday. [Tried to attach a screenshot, but it's rejected as too large]
Phil - I saved two of the Waypoints to "My Places", moved them to a test-folder, exported to kml, used GPSBabel to translate to Garmin gdb format. Worked just fine, but the problem is that there are so darned many points it would take hours to translate the complete waypoint list. Since Google Earth doesn't complain about whatever is going on inside the kml file, I naively expected GPSBabel to handle it as well.
Matt - you wrote "Expecting a little to much from the GPSbabel to get the data from the link" and provided another link for me to try. That link gave me the same (empty) results on translation - did it work for you or was it just a possible suggestion? Sorry if I'm missing something obvious.
