You clearly feel very strongly about that.  Fine.  I'm removing "-Wundef" from my local compiler flags now.

I don't "insist" on using that warning; rather I found it useful: in conjunction with a consistent *convention* of testing with "#ifdef" it has occasionally helped me catch bugs in the past.  Yet it is no silver bullet: the opposite kind of bugs can happen too.

I'm fully aware the usage is "perfectly valid" C, but that and being however many years old doesn't by itself mean it's a good idea, of course.

On the other hand, I do believe consistency is important.  Presently Subversion code is self-consistent in using "#ifdef", apart from this one instance, while inconsistent with some (many?) other autoconf users, including APR, which use "#if".  If we still value consistency in this project, we should consider switching all our usage to "#if".  I'm not volunteering to do that.  And I only said "consider" -- I'm not insisting and I don't wish to prolong this discussion.

Ugh, I hate conflict.  Can we talk about some exciting technical design issue next please :-)
