Hi,

I' ve got a project which uses Boost.UUID and function_types.
When compiling for Windows-x86 I define BOOST_FT_AUTODETECT_CALLING_CONVENTIONS before including
<boost/uuid/random_generator.hpp>
thereafter I include
<boost/function_types/config/config.hpp>

but then "boost::function_types::stdcall_cc" is not defined.
There seems to be a problem with the define/undef of the macro "callable_builtin" in <boost/function_types/detail/encoding/aliases_[un]def.hpp>

When I first include <boost/function_types/config/config.hpp>the type "boost::function_types::stdcall_cc" is defined.
I'm not sure if the define/undef of the macro "callable_builtin" could even violate ODR.
