Great, thanks.  I actually have no slightest idea why it compiles in VC7.1
without this "using" directive :)

Do you mean you forced it to use my encoding/decoding stuff?  I tried this
at some point with g++ 3.3, and got rather stupid complain, something like
mpl::int_<n>::value being non-constant expression...  I will try it once
more...

Do you mean in compiler_config.hpp, to easily distinguish between those
compilers that have native typeof support and those that don't?  In this
case we have to be more specific, because, for example g++ uses "typeof" and
Metrowerkes uses "__typeof__".

Or do you mean forcing compilers to use encoding/decoding even if they do
support typeof natively?  In this case it is library-specific, and I would
call it something like BOOST_TYPEOF_DISABLE_NATIVE_SUPPORT.
