Windows makes this simpler -- the system calls are separate
from the C runtime. It would be nice if Posix systems were that
way, but it's both silly to reinvent the system calls (they are
on every OS anyways, and in shared-library form), and a
maintenance nightmare.
Keep in mind that we only need to implement the system calls that
we need. I haven't looked into Phobos, and probably never will.
My interest is mostly in druntime. At this time, I think we only
need 2: `sbrk` and `mmap` for `malloc`. I don't consider that
much of a maintenance burden, and `malloc` and friends are my
least concern at the moment.
We're disproportionately leveraging libc in druntime; there are
only a few things needed from libc for druntime, and I think I
can demonstrate benefit writing them in D (or if someone else
wants to, please do, I may never even get to it).
If I even stick around in the D community long enough to pursue
this, this change it'll be incremental and I'll demonstrate
benefit each step of the way.
