Earlier on "the Work" is defined to be the source code I believe.

It's a much weaker "non viral" copyleft than the GPL because it defers
to any of the compatible licences listed at the end if combined into a
work consisting of multiple licenced codes. I had understood that to
mean that if your EUPL code is used as a library in a bigger project, no
obligations to distribute source land on the licensee, but if they
distribute a modified copy of your library as a standalone thing, then
they can't supply prebuilt DLLs without source code.

But that requirement, now you make me think about it, does violate the
Boost licence which does allow people to derive from Boost and publish
binaries without source. Good catch.
