- Druntime.
- Phobos.
- Possibly a little help from the compiler with module support,
(possibly emulated) tls, and adding ranges for GC scanning.

I've been testing/developing gdc pretty much solely off my (Android)
phone since the start of this year, and though I haven't committed
anything to trunk yet, shared library work on OSX is pretty much
feature complete - though don't ask me how I got gcc-9 working on OSX,
I still have no idea myself, as the last supported version of gcc
(4.2) can't build a working compiler from any of the recent releases,
and druntime's core.cpuid uses opcodes that are unsupported by the
default version of Xcode that came with the box. :-P

As for the toolchain though, both Apple and Google have abandoned gcc
in these respective toolchains, shame on them really.
