Well, there is obviously a mistake in the docomentation, but here is
the correct answer: __argc is really     extern char **__argc
this means that __argc is not the name of an array, but a variable
containing a pointer to a pointer to char. The latter tells the compiler
it has to do three levels of indirection to get to the actual char,
while the former implies only two. Hence the suggested solution works,
but it is not elegant nor necessary.

I suppose this should be done on comp.lang.c or something,
but the question was originated here...

                  Hope this clears the fog,
