Originally, I thought the problem was caused by a function that gets
called as a normal function where we want to return a value, and as a
signal handler where we need to have it accept a parameter (the signal
number) and it returns nothing, I was going to case the function name in
the signal call as (void (*)(int)).

Looking at all the source, it turns out this function only gets used as
a signal handler, so I set an int parameter and return void.

I have removed the Linux defines because they are not needed.  BSD let
this sloppiness slide.  Linux gave a compile error.
