hi;

I do not know if this is what you refer to or not, but gcc can generate,
_automatically_, a dependency file (.d extension) using the gcc -M flag. Then
this .d file is included into the Makefile, in the fly, and hence
used by Make to know the current dependency.

So, this step is automated, and programmers do not need to know the
dependency graph of the entire software really.

Here is a link that describes this and more , called
"Advanced Auto-Dependency Generation"

http://make.paulandlesley.org/autodep.html

The point is, there are ways to build this dependency automatically
in the C world. (ofcurse, the Ada way, with gnatmake is so much simpler and
easier, since this is all part of the language itself and not part
of the build 'tools', but if one is using C and C++ then there ways to do
this).
