I think this will lead to cyclic dependencies.

a.c: a.h b.h c.h
a.h: a.c

b.c: a.h b.h c.h
b.h: b.c

before we can build a.c we must build b.h->b.c but before we can build
b.c we must build a.h->a.c.

What I was thinking was to make each .o files depend on all the .c
files of the imported modules, ensuring that the .o file is not build as
to such time all the .c files and the corresponding .h files are built.

If I want to make it all the .c files in the current directory is there
already a utility predicate which lets me find that information?
