Add a cast to allow building on ILP32 systems (#101)
Add a cast to allow building on ILP32 systems (#101)

On architectures where `c_long` is an `i32`, e.g., OpenBSD/i386, the
comparison between `ret` and `u32::MAX as i64` is a type error.
Add a cast to satisfy the type checker on such architectures. This
cast is a noop on systems where `c_long` is an `i64`.
