I think that the performance of the non-integrated CPP is not
important for 3.0.  It is important, in fact, only that the total time
taken by `gcc -c foo.c' be comparable to 2.95; we can choose to speed
up any part of the compiler to accomplish that.  In other words, if
cpp is slower, and the compiler is faster that is OK.  

What would be nice would be if CPP were faster, and since integrated,
even faster, allowing us some slop for slowdowns in the compiler
itself....
