I presume those tests only use the _default_ build system, not ECL's
extensions. Your patches were produced against 1.5 and there the
OUTPUT-FILES would only return one file, even for ECL.

However, once we integrated ECL's extensions, these produce  two object
files, and I fail to see from your patch how the output files are handled --
from what I can see, since the OUTPUT-FILES method does not have an :AROUND,
the output of ECL's extensions is not translated: they just take the source
file produce a compile-file pathname and that's it. In other words: it is
going to work, but it is going to have files laying around, both translated
and not.

I suppose in your model developers are expected to integrate an explicit
call to component-translate-pathname in every method they define for
output-files.

Indeed, I find this an interesting approach, independently of what method is
used for translation, but I see a problem if a user decides to temporarily
deactivate translations or change the destination of a system. Right now it
amounts to changing the translation table. With your model it involves
re-reading and rebuilding the system and components.
