lint - "struct/union" warning question

[Mark Biggers]

I rely on and essentially "program for" lint, in the course
of my C programming.  So, I am quite familiar with *most*
of its helpful (and not so helpful) messages, EXCEPT:

warning: struct/union ptbl never defined
(and)
warning: struct/union proc never defined

and the line number these warnings refer to is always at the
end of the C source file.  Any one have a pointer to what
these refer to?
