Tools to support removal of unused header files

[computezrmle]

If a library function is added to a source code file for the first time it sometimes happens that the related header include gets forgotten.
This isn't a big problem since the compiler complains about that.

In case a function call is removed and given that call was the last call to the function the header include becomes obsolete but it often remains in the source file, sometimes for years.

I wonder if there are tools to support removal of unused header files.
Not necessarily automatic but at least to make the programmer aware of possible candidates.
