Scary error messages in the log

[nsabovic]

I'm trying to figure out why the standard VSCode C++ plugin scans my compile_commands.json-based project just fine but cquery shows undefined macros. I am using cquery HEAD installed with Homebrew on macOS 10.14.2.

Both the VSCode plugin and /usr/local/Cellar/cquery/HEAD-70c755b/bin/cquery --check spit out these messages in the log:

What is the normalization message? Should cquery built with -DSYSTEM_CLANG=ON look for cquery-clang?
