Anyone have any pointers to a diff for C code.

I have two libraries, A and B.

B is and expanded and modified version of A and I have been
asked to extract A from B to build two libraries one
built on top of the other.

What I think I need is a program which parses C and will
do diffs at the level of functions, globals , #defines and enums.

it would ideally have two input files and generate two outputs
one output being the common code, one with the extensions on the common.

I don't expect this to be fully automated, there is going to be a load
of hand edition before I am done, but is there somthing which can do
the easy stuff for me?
