This is on linking the DMD executable.

Xcode 7.3.1:

---
$ clang --version
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
---


Host DMD from Homebrew:
---
$ dmd --version
DMD64 D Compiler v2.071.1
---


This seems to be fallout from translating msc.c to D.
