Not difficult, but a tedious amount of work for no inherent 
benefit:
You would have to recreate the correct system call calling 
semantics for every operating system / hardware combination that 
D is supposed to run on.
I suggest reading [1] and [2] to get a feeling of the workload 
*just* for Linux.
My unsolicited opinion: Unless someone pays you (for whatever 
reason) to explicitly not use a libc, just use a well tested libc 
for system calls and be done with it.
