[boost] [patch] using boost/version.hpp

Dear Boosters,

I am trying to keep some backward compatibility (for some while) for the boost 
libraries we use in our codes (ublas for example), and I find that the  
addition below to boost/version.hpp helps a lot with readability in the code 
instead of using 

//  BOOST_VERSION % 100 is the sub-minor version
//  BOOST_VERSION / 100 % 1000 is the minor version
//  BOOST_VERSION / 100000 is the major version

-------------------
define BOOST_VERSION_MAJOR 1
#define BOOST_VERSION_MINOR 33
#define BOOST_VERSION_SUBMINOR 1

#define BOOST_MAKE_VERSION( a,b,c ) ((a)*100000+(b)*100+(c))

#define BOOST_VERSION \ 
BOOST_MAKE_VERSION(BOOST_VERSION_MAJOR,BOOST_VERSION_MINOR,BOOST_VERSION_SUBMINOR)

#define BOOST_IS_VERSION(a,b,c) ( BOOST_VERSION >= BOOST_MAKE_VERSION(a,b,c) )
----------------------------

In order to test the current version of boost:
#if BOOST_IS_VERSION(1,33,0)
  ... write the code according to the API >= 1.33.0
#else
  ... write the code according to the API <  1.33.0
#endif

would that be of interest ?

Best regards
C.
