Compile without standard library

[Ragmaanir via digitalmars-d-ldc]

Hi,

i want to compile D-code for an experimental OS.

But when i run the build script i get several compilation/linkage 
errors:

It looks like this is some d-internal stuff. What can i do to fix 
this? I have written some of my experiments in c++ previously and 
that works, but i want to port it to D because i think i will be 
more productive and less annoyed by the syntax. But this problem 
blocks me from doing so and i'm not sure about how to fix that.

Thanks!
