Diffs from 2.95 are likely to be extremely large: for a diff to remove
a library it has to include it verbatim, similarly to add one.  This means
the diff has to include all of the 2.95.x libchill, libio, libstdc++, and
all of gcc/ch to delete that, plus all of libstdc++, java, and libjava to
add that, on top of all the other differences.  In the end, the diff is
going to be almost as big as the distribution, meaning that it's not
worthwhile.

However, we do package a C-only subset (gcc-core-xxxx.tar.gz); for that,
the diff from 2.95.3 might be worth having.
