Comment (by JDLH):

 > When I say make sure your Xcode and your CLTs match, I mean to check
 that your system is coherent and not buggered by a mismatch between
 toolchains, which is a bit too easy to have happen. Specifically, these
 three things should match:

 Here are my versions for those tools:
 {{{
 % /Library/Developer/CommandLineTools/usr/bin/clang -v
 Apple LLVM version 10.0.0 (clang-1000.10.44.4)
 Target: x86_64-apple-darwin17.7.0
 Thread model: posix
 InstalledDir: /Library/Developer/CommandLineTools/usr/bin
 % /usr/bin/clang -v
 Apple LLVM version 10.0.0 (clang-1000.11.45.5)
 Target: x86_64-apple-darwin17.7.0
 Thread model: posix
 InstalledDir:
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
 %
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
 -v
 Apple LLVM version 10.0.0 (clang-1000.11.45.5)
 Target: x86_64-apple-darwin17.7.0
 Thread model: posix
 InstalledDir:
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
 % whereis clang
 /usr/bin/clang
 }}}

 So, my `/Library/Developer/CommandLineTools/usr/bin/clang` is a bit older
 than `/usr/bin/clang`, but the latter clang matches the clang within
 Xcode.app, and the latter is what gets used if no path is specified.

 How do I change my `/Library/Developer/CommandLineTools/usr/bin/clang` to
 be consistent with the other two?
