Paolo,
I don't understand. libstdc++ headers are brought in by #include directives. It
looks like in 3.5 more stuff is included, and the difference results in 10% of
compile-time difference.
Now, when the file is already preprocessed, CPP really has to do nothing but
tokenize the stream. I do not understand why you think this to be a CPP bug.
Would you care explaining?
