Even though there is no harm since argv[argc] is a null pointer 
and *argv[argc] is not accessed, "<= argc" is fingernails on a 
chalkboard, neverminding the novel use of argc to control non-argv stuff. 

If one is going to loop on argc, the C idiom is preferred: 

    for (i=0;i<argc;i++)

Also tolerable, but less readable, would be: 

    while (*argv++!=(char *)0)
