Re: xdc: A hypothetical D cross-compiler and AST manipulation tool.

llvm should be platform-independent enough, so you have ldc. But 
the problem with D is that it has more features than C/C++, so if 
you output C code you can only use C features, or you have to 
implement druntime+phobos for the target platform, which doesn't 
come for free.
