One possibility is to check for versions.  Better is maybe to do it  
like this

(condition-case nil
    (org-no-warnings
      (start-process-shell-command with four different args))
   (error
    (start-process-shell-command with three args))

Thill try one version, and if that given an error, try the other one.
To get rid of the compiler warning, wrap the call into org-no-warnings.
