[Win32] Use spawn instead of exec for main octave wrapper executable. * src/main.in.cc (prepare_spawn): New function, copied from libtool. (octave_exec): Use it and call spawnv instead of execv (note: execv kills the current process, instead of replacing it). (main): Make sure argv[0] always points to the executable, required by libtool wrappers.
