fix definition for Init_Machine
fix definition for Init_Machine

Declaration for Init_Machine in machine.h does not match definition in machine.c.
Declaration updated to match arguments used in stackl.c.
For some reason this is not an issue when compiling as C code, but is a compiler error when compiling as C++
