Hmm. 

include/bits/basic_string.tcc has:

  template<typename _CharT, typename _Traits, typename _Alloc>
    const typename basic_string<_CharT, _Traits, _Alloc>::size_type 
    basic_string<_CharT, _Traits, _Alloc>::
    _Rep::_S_max_size = (((npos - sizeof(_Rep))/sizeof(_CharT)) - 1) / 4;

So it's defined, or should be. Maybe implicit instantiations of class 
templates doesn't instantiate nested class static data on AIX?
