May need more work after #7800 and #7803, so I'm leaving it as a draft for now.

Seems a bit convoluted but as I do not understand this kind of processing well I leave it up to others to comment.

Still some notes.

For some additional extended manual testing you could use the invocation added in cppcheck-opensource/simplecpp#438 and adjust it for Cppcheck and compare the output. The standard headers have lots of templates after all.

Thanks, I'll take a look at that

Not in the scope of this PR but I wonder if it would make sense to add a debug message if a function is being omitted from analysis.

Any progress on this?

Sorry, stuff got in the way... I will take a look at the manual testing this week.

I've found some unhandled cases in stdlib headers so I'll be taking a look at those.
