If you can use a modern compiler that supports variadic macros (thus 
BOOST_PP_VARIADICS=1), then AFAIK it should support any size (up to 
whatever your compiler's limit is).

This may require telling your compiler to compile in C++11 or later mode.

Alternatively you can try forcing it on by #define BOOST_PP_VARIADICS 1 
before including any Boost headers (in all translation units), but this 
is less preferable.
