automatically finding c dependencies

i'm mandatory support tide digest lists .c files any lists each .h record directly indirectly enclosed file.

this infinite project, nonetheless have makefiles theoretically have information, those makefiles infrequently crude (we hereditary digest another company). we've mostly make purify ; make the changes indeed reflected recompilation, i don't wish rest makefiles.

so there apparatus lets us give name .c record an consolidate route have tell us .h files directly indirectly enclosed .c file? don't have anything uncanny like

#define my_include "some_file.h"
#include my_include

so apparatus doesn't need perfect. anything searched .c .h files an consolidate route unchanging includes good enough.
