Your 2nd example is something different and obviously a bug (using a function 
before it has been declared).

However, in pbuf.c, pbuf_free_ooseq() is implemented at line 115 (where it 
warns!) and used in line 143. This is a different kind of warning, which I 
haven't seen yet. The only purpose that I can see for this warning is to 
prevent unused global functions (so making it static would be the fix)?
