No, nobody suggested anything :-(
As I said, I think we can just drop the assignment to CFLAGS in HEAD
and 8.3, relying on configure to get it right.
After looking at the pgxs documentation, I think that the right
thing is to set PG_CPPFLAGS rather than CFLAGS from
the output of xml2-config --cflags. That should work for as far
back as we were using pgxs, anyway.
