Hi,

the attached source code is copied from
boost_1_33_0/libs/graph/example/adjacency_list.cpp, I only changed the
edge container to be slist, and include <slist.h>

I compiled it on linux with AMD opteron 844 processor.
gcc2.95.3 works fine, but gcc3.3 doesn't compile.
I think the reason is slist is not in std namespace in gcc3.3, and
adjacency_list.hpp doesn't handle this correctly for slist.

> grep BOOST_STD_EXTENSION_NAMESPACE adjacency_list.hpp
adjacency_list.hpp: typedef
BOOST_STD_EXTENSION_NAMESPACE::slist<ValueType> type;
adjacency_list.hpp: typedef
BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type;
adjacency_list.hpp: typedef
BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type;
adjacency_list.hpp: struct bind_ { typedef
BOOST_STD_EXTENSION_NAMESPACE::hash_set<T, std::less<T> > type; };
adjacency_list.hpp: struct bind_ { typedef
BOOST_STD_EXTENSION_NAMESPACE::hash_set<T, std::less<T> > type; };

 should slist be handled the same way as hash_set ?

thanks
weiqing
