Druntime: Changing the underlying C Standard Library

[Sebastian Trent via Digitalmars-d-learn]

Hello,

I'm writing an operating system in D for some exotic hardware. I 
understand the D runtime environment depends on a C stdlib being 
available (at compile time or run time?)

As a consequence of the hardware, I need to use our own C std lib 
for the operating system. How can I set about directing the 
compiler (or run-time) to non-default implementation?

Alternatively, I infer there's nothing breaking about replacing 
all of core.stdc with an implementation written in -betterC?

Thanks,


ST.
