Questions about cpp, cpplib, and precompiled headers

[Doug Landauer <landauer at apple dot com>]

I have a few questions, ultimately about precompiled headers.

I looked through the egcs mailing list archives, and found some
mention this past May:
   http://egcs.cygnus.com/ml/gcc/1999-05/msg00007.html
and its followups (messages 9, 11, & 12).  And the Cygnus
announcement at

   http://www.cygnus.com/news/corel.html

But the subject is not mentioned at the list of cpp-related
projects that still need to be done, at

   http://egcs.cygnus.com/proj-cpplib.html

So... my questions are:

1. What is the status of the Corel-related work mentioned in
     Cygnus' press release?

2. How close is cpplib to replacing the separate cpp?

3. Are these two efforts completely separate (other than both
     being based on the existing, earlier cpp)?

4. What can we do to help?

   Thanks,
