cccp.c (macro processor)

[Wu Ping]

Hi, all,

I want to know some knowledge of GNU C preprocessor. I am a student and
now is doing a survey of it. Please give me some idea. I have searched on
your website, but no information that I need.

So I ask you to just say something briefly about the
architecture of cccp.c(the C preprocessor), the main internal techniques
involved....

I really need your help! Please........

Thank you very much!
