Use die() here, that's what it's for.

die() doesn't print file and line information.

Don't we need a different case here somewhere for if someone specifies
an include file as an absolute path?  Have I missed something?

Yeah, I forgot about that, and sent another patch to fix it when I
noticed (jdl had already pulled, so I didn't send an amended patch).

I wouldn't suggest a doubly linked list here.  Or at least not without
converting our many existing singly linked lists at the same time.

The doubly-linked list is intended to make it easier to construct search
path lists one-at-a-time from arguments in the proper order, without
needing to reverse the list at the end.
