It's not only fsync, though - there would be a lot of duplicated code if
we were to convert all function pointer passing back to function calls.

Also, if the system is lacking a function prototype, at the minimum, the
compiler will give a warning - at worst, we invoke the function 
incorrectly, causing a crash.
