I've run into this one before myself.  If you read K&R carefully, two
structures can have components with the same names *only* if the
components are of the same type and at the same offset from the
beginning of the structure.  Many C compilers have departed from K&R and
fixed this particular brain damage long ago -- I've been told that
the ANSI C standard does not impose any similar restriction.

It would be nice if Alcyon at least provided a warning about duplicate
component names, but C has never been known as a language that provided
good compiler diagnostics....
