I have had this happening for a couple days, and don't see any
reason for it, as the files haven't changed, unless an include
file is messed up somewhere. (I suppose there could also be a
corrupt file here, but I mention it in case somebody changed 
something that isn't quite done yet.

This is on a dec alpha multia running the latest snapshot, trying
to build -current.
