[sigc] ANNOUNCE: libsigc++ 1.9.11

[Martin Schulze <martin-ml hippogriff de>]

*** libsigc++ 2.0 (unstable)

libsigc++ implements a typesafe callback system for standard C++. It
allows you to define signals and to connect those signals to any
callback function, either global or a member function, regardless of
whether it is static or virtual.

libsigc++ is used by gtkmm to wrap the GTK+ signal system. It does not
depend on GTK or gtkmm.

libsigc++ 2.0 uses modern C++ mechanisms to achieve a highly flexible,
yet typesafe callback system. It supports all features of libsigc++ 1.2
and improves upon it with a simpler and more powerful API.

This version of libsigc++ needs GNU g++ 3.2 or higher to compile.

*** Changes:

1.9.11:

API Additions and important bug fixes:
* Compatibility module completed. libsigc++-1.2 filenames are
  preserved.
* Fixed critical bug in auto-disconnection: don't defer detaching
  of a slot from all referred trackables during signal emission.
* Reduced size of slots significantly.
* Fixed support for sigc::ref() in adaptors.
* Fixed sigc::visit_each(): only hit targets that are passed by
  reference; pass bound members in bound_member_functor by reference.
* Add lambda actions sigc::{reinterpret,static,dynamic}_cast_
  to support explicit parameter conversion.
* Add adaptors sigc::retype_return<>() and sigc::hide_return().

Minor fixes:
* Fixed return type deduction for bind<0>.
  libsigc++-1.9.11 should compile with gcc-3.3.
* Fixed copy constructor and operator=() of slot template.
* Fixed a compiler warning in signal_emit#<>::emit().
* Improved test case.
