--- Comment #1 from kinke <kinke at gmx.net> ---
AFAICT, the problem is that DMD generates the temporary preprocessed `.i` in
the same dir as the `.c`, just with the extension replaced:
https://github.com/dlang/dmd/blob/fa7a1b3d9f4e89d4a6b44ec57ed1f5137c303694/compiler/src/dmd/cpreprocess.d#L88

LDC creates a unique temp directory to hold the `.i`.
