Not necessarily; the way I had intended my suggestion to work was that
GDB always adds ".gz" (or some other suffix if we actually are not
compatible with the .gz file format) to *every* file it fetches, not
just to the initial target.xml, but also to other files fetched via
xi:include statements ...

If the compressed version of the file is not available, GDB would
then fall back to the original file name (on a file-by-file basis).

Bye,
Ulrich
