Sorry, I didn't look at the first version of the patch.  I think that the
cleanest thing would be to have files in include that mirror the .c files.
If we have to add too many new .h files, maybe we should combine some .c
files.

But please note in few places prototype is just before function

If you declare it as static that will silence the warning as well.  Of
course this only works when it is just used locally.
