The appended file t.C, a reduced version of the file boost/libs/disjoint_sets/
disjoint_set_test.cpp, does not compile. Gcc 3.4.0 built on 2004-03-05 or the 
day before accepted the original code. I am wondering whether it is legal. If I 
define elts as elts[4] the code compiles. When I make do_test a free function 
the code is also accepted.  
 
template <typename DisjointSet> 
struct test_disjoint_set { 
  static void do_test() 
  { 
#if 1  
    unsigned int elts[] 
#else 
    unsigned int  elts[4] 
#endif  
        = { 0, 1, 2, 3 }; 
    const int N = sizeof(elts)/sizeof(*elts); 
  } 
};
