I run a D program through the basic cmd.exe, it runs with no stdout buffering.
You'll find the same thing with C programs, since it is actually the C standard library that does this buffering rather than D.
If it is writing to a character device (the only one I've ever seen in practice is the Windows console, directly, not through a pipe meaning this doesn't occur for terminal replacements or IDEs or similar), it line buffers. Otherwise, it block buffers.
