The runtime is needed if you are going to use any of its 
features, like the GC. If you restrict yourself strictly to C in 
D (and that means avoiding thinks like builtin AAs, array 
concatenation, and anything that touches the runtime) you can do 
without it.

The functions you want are core.runtime.rt_init for 
initialization and core.runtime.rt_term for cleanup [1]. On 
Windows, you can guarantee these will be called by adding a 
DLLMain checking for DLL_PROCESS_ATTACH and DLL_PROCESS_DETACH. 
On other platforms, you'll need to work out something else.
