  Try instead:

        spawnlp(P_WAIT, defaults.dflt_ed, defaults.deflt_ed,
                defaults.last_file, NULL);

  The spawnlp() function, means that the arguments are passed in the call as a  
NULL terminated list and that the PATH is searched to find the program to be  
executed. The first reference to defaults.dflt_ed is the actual name of the  
program to be spawned. The second is argv[0] and unused by DOS, but still  
required. Finally the arguments are passed beginning with argv[1] which, in  
your case, is defaults.last_file.
