In the following code fragment, all of the functions suffer from the
same type of error, i.e. that they all declare their parameters in
terms of structured types which cannot be used EXCEPT within the functions
themselves (or perhaps just within their formal parameter lists).

Unfortunately GCC 1.35/sun3 only flags the first three functions with
warnings and doesn't even mention the other cases.  I believe that
all these cases should be considerd errors.  At the very least, they
should all ellicit warnings from the compiler.

A good case can be made for errors, especially for the functions which
are absolutely impossible to call (from outside).  The ones that are
impossible to call are the ones that use prototypes and also declare
some parameter to be of a (hidden) struct or union type.
