Hi, 
GCC-4.1.1 gives me the attached error message while compiling
dynamic_image. 

It boils down to: 

dynamic_image.cpp:14:   instantiated from here
boost/mpl/aux_/preprocessed/gcc/template_arity.hpp:85: error: call of overloaded  'arity_helper( aux::type_wrapper< .... >,aux::arity_tag<1>)' is ambiguous
boost/mpl/aux_/preprocessed/gcc/template_arity.hpp:30: note: candidates are: char (&aux::arity_helper(...))[1]
boost/mpl/aux_/preprocessed/gcc/template_arity.hpp:37: note:                 char (&aux::arity_helper(::aux::type_wrapper<F<T1> >,aux::arity_tag<1>))[2] 
boost/mpl/aux_/preprocessed/gcc/template_arity.hpp:37: note:                 char (&aux::arity_helper(::aux::type_wrapper<F<T1> >,aux::arity_tag<1>))[2] 

Is this a known mpl<->gcc-4.1.1 issue?

Furthermore there are some odd warnings, and I am not
sure what to think about these. The code there looks a bit fishy. 

I tried the example with gcc-3.4.4, gcc-4.2.0-alpha20060902
and gcc-4.3.0-alpha20061111. It compiled there, but the warning
remained in the gcc-4 series.
