Generating a call tree or abstract syntax tree in a mixed source code?

Question

I am looking for a tool to generate a call tree or abstract syntax tree from a mixed-source code, consisting primarily of FORTRAN (some 77, mostly 90) and C++ (with a smattering of plain-old C). Ideally it should be free/open source. On the commercially available end, I have seen Understand, are there others?

Edit I am using the Intel Fortran and C++ Compilers.

Also edit I'm running Linux. I've also used the Intel VTune utility, but that only gives the call graph for a particular instance (e.g. one branch of an if/then switch), not the complete structure.
