Explanation:
I do some competition programming and would like to write it in D 
instead of C++ :)

That's quite nice, but not what I'm looking for.
What Calypso does, as far as I can see, is to make it possible to 
compile C++ and D together. I'm looking for a compiler that takes 
in D code and spits out either C or C++ code.

I can't imagine that's been done, and I'm not sure it will be 
high on anybody's list of priorities I'm afraid. A lot of work 
was done on automating C++ -> D, but converting D, a language 
intended to replace C++, to C++ itself seems a little backwards. 
I get why you'd like to use it, but I don't think it's been done, 
sorry.

Given that you can call D from C++, I don't see the need for such 
a tool.

Your best option would be to use LDC with a C backend:
https://www.google.com/search?q=llvm++c+backend
No idea how well supported this is, I've never used LLVM myself.

Julia guys resurrected the C back end for LLVM.  Chap here posted 
about using this to compile D to bitcode to C to JS (last but 
using emscripten).  Even without last stage,  doesn't sound a 
great idea if you are under time pressure,  as the whole process 
is quite fragile.

It would be nice to have a robust C backend, even bearing in mind 
all problems with UB and difficulties one can imagine that might 
cause.
