Do you mean adding 'INCLUDED FROM' index at the head of *.h files?

        +-------------------------------------------
        |libutil/die.h
        |
        |/* [<][>][^][v][top][bottom][index][help] */ 
        |-------------------------------------------
        |DEFINITIONS
        |
        |This source file includes following functions. 
        |
        |-------------------------------------------
        |
=>Add   |INCLUDED FROM
        |
        |This source file referred from following places. 
        |
        |       libutil/die.c                   ===> go to '#include' in die.c.
        |       ~~~~~~~~~~~~~
        |       gtags/gtags.c
        |       ~~~~~~~~~~~~~
        |       ...

I think it is possible. For example,

1. Pick up all of '#include'.

        % global -xg '^[ \t]*#[ \t]*include'
        ...
        ^[%20\t]*#[%20\t]*include   30 libutil/global.h #include "die.h"
        ^[%20\t]*#[%20\t]*include   31 libutil/global.h #include "find.h"
        ^[%20\t]*#[%20\t]*include   32 libutil/gpathop.c #include <strings.h>
        ^[%20\t]*#[%20\t]*include   35 libutil/gpathop.c #include "die.h"
        ...

2. Make index from 1.

        die.h ==> libutil/global.h(30), libutil/gpathop.c(35),...
        find.h ==> ...

2. For each include file, show 'INCLUDED FROM' index.

        die.h
        +--------------------------------------
        |...
        |       libutil/global.h        => libutil/global.h#30
        |       ~~~~~~~~~~~~~~~~
        |       libutil/gpathop.c       => libutil/gpathop.c#35
        |       ~~~~~~~~~~~~~~~~~
