[Michael Newton <kimbrr@xxxxxxx>]

For his patch
    Fix PCP start script regressions
Nathan wrote
    :
    Also ensure the $PCP_RUN_DIR exists, else pmcd fails to start from
    this script on Windows at least.

Im separatng this into a separate patch as i need to deal differently with
the other issues
