[boost] patch for tuple/detail/tuple_basic.hpp

From: Markus Schöpflin (markus.schoepflin_at_[hidden])
Date: 2002-09-20 06:35:48

Hello,

the appended patch makes the tuple library compile on more compilers. 
Especially it makes use of BOOST_NESTED_TEMPLATE for this. Could anyone 
please apply it, maybe also on the release branch?

Thanks, Markus
