How to size optimize the executable?

Some simple programs have almost 200 kb. I've tried packing them with kkrunchy,
the result are still about 100 kb. By contrast, with Visual C++ such programs
would be only a few kbytes (in release mode). Why is D generating such big
executables? How is it possible to get them smaller?

Well, one reason is because D has a larger runtime that includes things like GC.
Theoretically, this could be made into a shared lib, but I think there are higher
priorities in the D community.
