Good point. Reading http://ozlabs.org/~rusty/index.cgi/tech/2008-01-04.html makes me sad. -Wundef would be a lot more useful if autoconf defined symbols to zero instead of undefining them; then we could get rid of all the defined() calls, and the compiler could tell us when we'd misspelled a HAVE_XXX. Oh, well. - Dan
