Hi Domagoj,

I am on xbox 360 with visual 2005, PS3 with SNSystems SNC compiler and gcc compiler v 4.1.1.

I have tried your implementation and compilation fails at a STATIC_ASSERT:
BOOST_STATIC_ASSERT( is_stateless<base_empty_handler>::value );

A simple declaration of boost::function<void ()> f; will create this error.

A similar assert happens with SN systems compiler for the PS3.

When I use gcc, there are a slew of errors mostly pertaining to declaration order in function_template.hpp. I am not very familiar with this issue, but have tried to move code around, and defining functions out of class scope. Some errors go away, but there are a lot of compiler problems at least on my machine.

Here is the error on xbox 360:
1>boost-1.40.0\boost/function/function_template.hpp(183) : error C2027: use of undefined type 'boost::STATIC_ASSERTION_FAILURE<x>'
1> with
1> [
1> x=false
1> ]
1> boost-1.40.0\boost/function/function_template.hpp(641) : see reference to class template instantiation 'boost::function0<R,PolicyList>' being compiled
1> with
1> [
1> R=void,
1> PolicyList=boost::default_policies
1> ]
1> myFile.cpp(64) : see reference to class template instantiation 'boost::function<Signature>' being compiled
1> with
1> [
1> Signature=void (void)
1> ]

There were also some trouble when compiling templates that end in ">>" which AFAIK is not fixed on my version of gcc.

Do you know if your changes made boost.function less robust to older compilers ?
