Getting rid of excess #includes

[LionKimbro]

Is there a tool to help identify excess #includes?

That is, #include's that have no functions or preprocessor directives
that are being used by a source file.

PC-Lint (http://www.gimpel.com) will identify both includes and macro
definitions physically in a source code file that are not used.

It is a commercial product, not free. But it is also one that no
professional C programmer should be without.
