When you call a program with no arguments, argv[1] is a null pointer.  
While it is generally desirable that library functions be protected 
against such calamities, IMHO anybody who passes a null pointer to a 
library function is looking for trouble.  For example, try something like 
``strcpy (0, "You're gonna crash!")'' and watch the fun.

These two work for me as you'd expect; they even simulate (the
nonexistent) "." and ".." entries in the root directory.  What version of
DJGPP are you using?  `readdir' has been changed in v2.01, so maybe you 
are using an old version?
