I'm not sure what you didn't understand, so I'll just rephrase it:
in order for the output of cpp to be useful, you need to make sure that all
the #include do find the corresponding header file (also it'd be better if
the various predefined macros, via -D or built-in into the compiler were
handled correctly). This info is in general only available by parsing the
Makefile (or equivalent for people who use other tools).
Of course I can also manually take the relevant info from the Makefile and
put it into c-macro-cppflags, but doing that for each and every project
I work on is just too much trouble for me to even try it.
