Minimal ASTFrontendAction example
Our tool uses ASTFrontendAction/ASTConsumer to analyze C/C++ projects.
Sometimes we specify `SkipFunctionBodies` to optimize the process. I'm
attaching `clang_tool.cpp`, a minimal example that models what's happening.
Unfortunately `xgboost` fails to compile when `SkipFunctionBodies` is `true`:
```

There are similar errors for all the source files which include the affected
header file. I have an archive with `xgboost` and its dependencies, but I guess
it exceeds file size limit for this bug tracker.
Anyway I will be glad to provide you with any further information.</pre>
