There is another semi-automatic way for figuring out the dependencies.

For every .h file, put in the following stuff:

/* foo.h */
#ifndef FOOH
#define FOOH
/* !actual include! foo.h */

...

#endif

Run the .c file through CPP, then grep the output file for '!actual include!'.
This way, the dependencies can be obtained relatively painlessly.
