I was going to make a similar comment about this patch last month

	http://gcc.gnu.org/ml/gcc-patches/2000-03/msg00224.html

("Clean up cpplib's internal namespace") but I wasn't sure how
zealous we were about these things.  There are already a number of
these sorts of things in GCC, but it seemed a shame to introduce
new ones.

How draconian do we try to be about pedantic stuff like this?
