I guess there is no way of making compile time constants work with
compliant compilers...
But then compliant compilers don't need the compile time constants
typeof in the first place, as they can use Arkadiys implementation.

>From a quick search in boost/config, the compilers supported by boost
that does not support partial template specialization, are:
VC 6.5 and 7.0
Sunpro 5.2 and earler
MPW 

VC 6.5 and 7.0 are covered by my compile time constants implementation.
The question is whether the other two compilers are compilant enough
to have implemented ADL correctly :)
