155,Bug in edge.hpp:99 std::ostream is NOT a template,nobody,jsiek,"{{{
Compiling boost with Intel compiler I’ve got such an error:
g++  -c -Wall -ftemplate-depth-100  -

DBOOST_PYTHON_SOURCE  -g -O0 -fno-inline -fPIC   -

ph/detail/edge.hpp(99): error: type ""std::ostream"" may 
not have a template argument list
    std::ostream<Char, Traits>&
         ^
…

The problem is in graph/detail/edge.hpp:99:
  template <class Char, class Traits, class D, class V>
  std::ostream<Char, Traits>&
  operator<<(std::ostream<Char, Traits>& os,
             const boost::detail::edge_desc_impl<D,V>& e)

You should have known that std::stream is not a 
template - it is simply an end-user type defined as:
typedef basic_ostream<char, char_traits<char> > 
ostream;

So template arguments are not suitable for it. Gcc 3.2 
accepts the code because of an ugly bug in compiler, 
gcc 3.4 has this bug fixed, so it emits the same error as 
Intel compiler emits. The code in boost must be 
changed, I suppose you meant basic_ostream instead 
of ostream, with this assumption I’ve done the patch:
