This is not complete picture. The compete picture include
also following files:
  main.o
  foo.o  # maybe also libfoo.a
  main   # executable, aka 'main.exe'`

Dependency of main.exe is traced eventually to main.c,
foo.c, and foo.h. Only targets have dependencies (targets like
make.exe, make.o). The main.c is not a target.

Maybe you actually want to discuss
tracing the dependencies for 'main.exe' not for 'main.c' ?
