removed 3 forward declarations's inside of a fuction.

They were not needed were for functions that were in the same .c file
higher up and I think its sort of a non standard way of doing things.
(using prototypes would probably be more inline with the other code but
as I mentioned they are not needed and were causing warnings in gcc)
