I suspect that LDC allows LLVM to use an external function, but I 
dont know for sure. I would have to look over the code it sends 
to LLVM... But the beauty of Open Source is that it is easy to 
modify LDC!

Anyway, dont do this with C compilers, as they might refuse to 
inline functions with alloca to prevent the stack from 
exploding...

Very much a low level approach, but fun!
