I think there may already be a tool for this. From Adams et al.
(ACM Transactions on Software Engineering and Methodology, Vol. 3, No. 1,
Jan 1994):


"An environment analyzer separate from the compiler can afford a more
thorough analysis. It can process all units to detect spurious unit
dependencies and delete them. The program Incl [Vo Chen 1992] performs
this analysis for C programs. It is run periodically to "clean up"
a dependency architecture that might have undergone some deterioration
during maintenance."


I haven't read the orginal paper but the full reference is:


Vo, K.-P., and Chen, Y.-F., `Incl: A tool to analyze include files'.
In Summer 1992 USENIX Conference (San Antonio, Tex., June), pp 199-208.
