Tentative explanation: "Manifests" are embedded in binaries, and are
used to check dlls at load time.
python_d.exe contains the manifest for the debug dll: see the
"Embedding Manifest" step in the build log.
But sqlite3.dll was compiled "by hand", and does not contain manifest.
So there is no manifest at all for the release dll, and it will not
load.
