Arrays, AA, string switch, array ops, boundary checks, closures, exception  
handling, class factory, module constructors, unittests, RTTI.
Just to name some deeply integrated features that require runtime support  
and or heap allocation. Some of them even rely on GC in their current  
implementation.

Obviously you can compile and link a simple "double add(double a, double  
b) { return a + b; }" without using the runtime.

What's that thing about not using the C runtime? Don't you use malloc,  
atexit, str*?
