'What's the point of a `.inc` file in C++ & C? What situation would you want to use it?

I'm sure this is has been asked before and will be closed and marked as a duplicate but I'm having problems finding it...

For example, at llvm/lib/Support/Unix/Signals.inc within the llvm project. What's the point of using this suffix for a cpp file?

So the .inc extension is used to distinguish between auto generated headerfile vs manually written headerfiles.
