There isn't a final decision yet. One of the maintainers of the
preprocessor in GCC is adamant that preprocessing involves losing
information, and even though I have changes that prove otherwise, they
actually preserve more information than what the integrated
preprocessor passes to the front end, so we end up with different
debugging information either way.
The solution I've been using so far is to force distcc to not use
localhost in gcc bootstraps, by means of a distcc wrapper that
transforms localhost to `uname -n` in $DISTCC_HOSTS. I'm not happy
about it, but I haven't had more time to spend trying to get the
integrated preprocessor and the separate one to agree on the same
debugging information.
