 {{{
 Hello,

 recently i faced with problem - i was not able to pass weak_ptr to bind()
 function. I started to study why and found there is no support for this in
 boost.

 As result, me and my friend wrote "get_pointer" version
 which accepts weak_ptr.

 At actual call moment, implementation uses weak_ptr::lock() to get
 shared_ptr. If retrieved shared_ptr is invalid, then exception of type
 "disposed_exception" thrown.

 This code was tested on Windows XP SP2 with following compilers: VC6, VC7,
 VC7.1, VC8, g++ 3.2.3 (MinGW), g++ 3.4.4 (Cygwin).

 If you find this code is useful for someone else me, please add to boost
 (it's actually not a library, this is why i'm poosting it to "patches").
 You can find sources + test app in attachment.


 Thank you,
 Dmytro Gokun
