AW: AW: Writing a standalone c preprocessor (like the old cpp) using the cpplib

Thanks for the answer. I was already aware of mcpp, but I'd rather like to
stick with gcc's libs, because I am not sure whether the development of mcpp
is still in progress.

So, cc1 is using the libcpp and can be used as a starting point to understand
how the driver is using the lib? I just need a brief abstract overview of what 
things
are going on between the driver and the libcpp.

Thanks again for the help,
Oli
