Are you sure? If it was a simple pointer than this would be true, but it's a
pointer to a pointer. (Or an array of pointers if you prefer.) The following
does
not compile in MSVC6 SP5 (and I don't think it should):

void test(const char**) { }

int main(int argc, char** argv)
{
   test(argv);
   return 0;
}

error C2664: 'test' : cannot convert parameter 1 from 'char ** ' to 'const
char ** '
Conversion loses qualifiers
