So in this case we mostly need to include an internal header (epiphany-syscalls.h). In a few cases an explicit prototype is added. We've also got a return with no value in a function with a non-void return type. Finally the asm_syscall interface expects a pointer as its first argument. In a few cases we've actually got an int (file descriptor) which we just cast to a void *. It's slightly more than Jeff J's pre-approval, but I think still reasonable.
