Hi Chuck,

Well, actually I should have proceeded to test my theory, that is,
recent changes to the "cp" source caused the breakage.  Okay, maybe
the changes "should just work" and do not because of a compiler bug,
but I can say that when I

	cvs checkout -D "2 months ago" basesrc/bin/cp

and built the older "cp" with yesterday's -current, this "new old"
copy of "cp" appears to work like a charm.

Looks like utils.c has had some munging on the MMAP code beyond the
Ansification changes.

Your posting referenced above does not provide any intermediate details
or hints so I've no idea if what I have tried is part of the path you
took to ultimately conclude the compiler is broken.

Cheers,
