[PREDEF] Review for the Boost.Predef library by Rene Riviera

The review of BOOST.PREDEF by Rene Riviera is scheduled between Monday,

Contents & Scope
================
BOOST.PREDEF defines a set of compiler, architecture, operating system, 
and library version numbers from the information it can gather of C++ 
predefined macros or those defined in generally available headers. The 
idea for this library grew out of a proposal to extend the Boost Config 
library to provide more, and consistent, information than the feature 
definitions it supports. What follows is an edited version of that brief 
proposal.
