We have been planning to switch to cpplib as the default preprocessor
for more than a year now. All of the critical bugs that I am aware of
have been fixed, there's no performance loss and no regressions in the
test suite, it can handle glibc and X11.
Now there's a fairly messy situation with C++ comments (see
http://gcc.gnu.org/ml/gcc-bugs/2000-01/msg00637.html and the thread it
spawned) which I do not believe is practical to fix in cccp. There is
a minor issue of standards conformance involved, too - failure to
issue a mandatory diagnostic even in -pedantic mode.
Rather than continue to hack up cccp, I would like to switch on
--enable-cpplib by default in the EGCS tree. I am not going to go all
the way to --enable-c-cpplib yet because there are still some critical
issues with the integrated preprocessor (e.g. -save-temps won't give
you an .i file if you do that).
If there are no objections I will make the switch on Friday morning.
