sorry i don't think that came off how i meant it... what i mean is this is
kinda asking for trouble. what happens if the boost macro changes?

wouldn't something like this be better:

#ifdef BOOST_XXX
#define MY_XXX BOOST_XXX
#else
#define MY_XXX /* boost_lite thing here */
#endif

redefining a macro in somebody else's 'namespace' is akin to opening up the
std namespace to redefine vector.
