Hi!

Since this issue came up again here just now, I would like to draw your attention to this particular bug.
It hinders integration with widely used build systems like Automake, CMake, Meson and build tools like ninja/make and in general results in very suprising results especially when using templates in code that is split-built.

A patch is available in a PR against dmd, but there was no new activity since last March, so it would be nice to get feedback and have the change finally merged in some form.

PR:  https://github.com/dlang/dmd/pull/6961

Thank you and greetings from the Debian developer's conference in Taiwan (with more interest in D here than expected :-) )

Cheers,
    Matthias
