Right. overlap() expects "int"s, but some of the values passed are
changed to double by my patch. If a valid prototype is in scope, the
compiler will automatically cast them to int, otherwise it will pass
them as double.
All of those declarations in setup.h should be either fixed or
removed. If the compiler needs a prototype (because the function isn't
already in scope at the point that it's used), it needs the *correct*
