It looks like DMD is in a worse state, a simple reproducer script shows that
reverting the PR doesn't help DMD at all (using v2.091.1 as host compiler).

```
#!/bin/bash

mkdir -p build
echo "/etc" > build/SYSCONFDIR.imp
echo "v2.094.0" > build/VERSION

for dir in . root backend; do
    mkdir -p build/${dir}
    for src in src/dmd/${dir}/*.d; do
        echo dmd -version=MARS -I=src -J=src/dmd/res -J=build -c
-od=build/${dir} ${src}
        dmd -version=MARS -I=src -J=src/dmd/res -J=build -c -od=build/${dir}
${src}
    done
done

echo dmd build/*.o build/root/*.o build/backend/*.o -of=build/dmd
dmd build/*.o build/root/*.o build/backend/*.o -of=build/dmd

echo ===================
dmd --version
```
