[sigc] What is changed in sigc::bind?

[Igor Gorbounov <igorbounov topazelectro ru>]

Hi, All!
I've recently updated from Fedora Core 4 to Fedora Core 5 and now my
app compiles with errors in this place:

"Glib::Thread::create(sigc::bind<Glib::ustring, DataRec&>(sigc::ptr_fun(
receive_data), local_conf.curr_aggregate, datarecord), false);"

the complains are about my struct DataRec, transfered by reference:
"usr/include/sigc++-2.0/sigc++/adaptors/bound_argument.h: At global scope:
/usr/include/sigc++-2.0/sigc++/adaptors/bound_argument.h: In 
instantiation of Б─≤sigc::bound_argument<const DataRec&>Б─≥:
/usr/include/sigc++-2.0/sigc++/adaptors/bind.h:1452: instantiated from

sigc::pointer_functor2<std::basic_string<char, std::char_traits<char>, 
std::allocator<char> >, DataRec&, void>, Glib::ustring, const DataRec&, 
sigc::nil, sigc::nil, sigc::nil, sigc::nil, sigc::nil>Б─≥

/usr/include/sigc++-2.0/sigc++/adaptors/bound_argument.h:69: error: 
forming reference to reference type Б─≤const DataRec&Б─≥"

and there is still a lot of such stuff omited here.
So something has changed between libsigc++ -2.0.11 (Fedora Core 4) and 
2.0.17 (FC5).
And this something interferes with references.
