These files are part of the runtime environment. Since you're not 
targeting an OS, you're going to need to roll your own runtime 
environment. Unlike C, D cannot function without a runtime environment. 
I would recommend looking at Tango's lib/ directory and starting from 
there. The GC is probably the only part that will need significant 
change to be rolled into a kernel.
