Title: Use _spawnvp instead of _execvp on windows for ecl command line for candidate-3.4.0

Even microsoft's example for the exec functions seem to have issues
on windows. After exiting the command shell seems to be in the proper
state but the prompt doesn't appear until after the next action.

Its quite confusing for the user.
