Looking for a free source code analyzer (Function depedency tree) [closed]

Question

Does anybody know where I can find a utility/application running on Windows that analyses C source and outputs a functional dependency tree?

What I'm looking for is something along these lines:

PrintString->PrintCharacter->PrintByte->Printf

It's almost certainly overkill, but you can do this for C, C++, PHP, Java, C#, and more with Doxygen (if you have Graphviz dot installed). Here's a page with a sample call tree generated by Doxygen/dot.

Doxygen runs on Windows fine, and can output HTML and a few other formats.
