-Try:

-     /* newsize is the size of your expanded argv array */
-  for (ctr = OLDargc; ctr < newsize; ctr++)
-	argv[ctr] = (char *) 0;
-  /* now append arguments to your heart's content.. */

There is nothing particularly Pascal-ish about this.  It is, however,
wrong.  argv[] is not allocated by malloc(), or not guaranteed to be so
allocated, and therefore it is wrong to call realloc on it.
