Never mind - problem solved.  Seems that sup didn't get me the newest 
version of sys/param.h today.  I wonder how much more I may have missed.

Yup.  Here's the RCS Id lines from the relevant files.  And I've used 
diff to verify that the /usr/sys/include versions of the .h files are 
identical to the src/sys/sys versions.

Looks to me like ps didn't learn its lesson!  :)  Either that, or one of 
these files changed more recently and sup didn't grab it.
