execv(cmd, arg0);
execv(cmd, arg0, arg1);
execv(cmd, arg0, arg1, arg2);

Yep, this is possible, but looks insane.

I'm working on a solution like:

procedure t is 
  argsstring : constant C_String_Collection :=  -- limited type 
    "/usr/bin/sh" & ASCII.NUL & "-c" & ASCII.NUL & "xxx" & ASCII.NUL;   
  args : C_String_Array;                  -- contains address of collection
  envstring : Enviroment_Collection(1 .. 400); 
  env : Enviroment;   
begin     
  Array_From_Collection(argsstring, args);     

  Bind_Enviroment(envstring, env);        
  Add_Enviroment("HOME", "/var/home/lutz");          
  Add_Enviroment("USER", "lutz");            
  
  execve(To_Fullpath("/usr/bin/sh"), args, env);               
end t;
