Info files are almost plain ASCII files, so you should be able to browse them with your favorite text file browser or editor. You will lose the hypertext structure and you might have hard time finding the next chapter (hint: look up the name of the Next node at the beginning of this node, then use grep to find that name), but other than that you will see all the text.

Anthony Appleyard has translated the Info files for GNU C/C++ Compiler (gcc.iNN) and GNU C Preprocessor (cpp.iNN) into ISO-8859 (aka plain ASCII), and Stephen Turnbull has made them available on his anonymous ftp and WWW server. You can get them by anonymous ftp to turnbull.sk.tsukuba.ac.jp, directory pub/djgpp/doc, files gcc.txt and preprocessor.txt; or point your Web browser to this URL:

http://turnbull.sk.tsukuba.ac.jp/public-ftp/djgpp/doc/

and get the files gcc.txt and preprocessor.txt.
