[ec]*tags would probably be adequate for finding duplicates. 
For ctags, -d adds #defines, -T adds typedefs and tags; -v vgrind or
-x cxref output formats may be easier to work with. 
I've use cxref to help clean up code before major surgery; presumably
cscope would work as well. 

With (suspected) dead code, I first put it inside #if 0...#endif,
check it still compiles and passes tests, check in the source, delete
the conditional code, check it still compiles and passes tests, check
in the source again; saves having to revert deleted code if you
