It happens when compiling the driver and support files from Scyld,
but I've not seen it happen with other files. I'm running Gentoo,
and the whole system was basically built up from sources without 
much in the way of errors. But I wouldn't be surprised if there's 
something goofy going on with with the include files. I'll get a 
fresh copy of the kernel sources and try again tonight.
