Imagine that we have a project and we build it with GCC, we have `compile_commands.json` file which  contains all compile command used to build this project.
Now we are trying to use clangd for this project, but as it turns, `__GNUC__` is equal to 4, but we expect it to be equal to compiler version which was used during the build.

We are talking about clangd -- tool, which provides IDE features, I expect it to be compatible (as much as possible) with a project which was built with GCC
