Beyond the points mentioned, I believe a version macro could be
useful on a user-level:
#if BOOST_VERSION < 0102101
#error This program needs boost 1.21.1 or later
#endif
The version macro should only rarely be used to provide
backward compatibility in user programs, since boost libraries
should try to be source-level backward compatible.
(We do have some liberty to make more radical cuts, should the
need arise, unlike the C++ standards committee (see vector<bool>).
[Please adjust the arithmetics in my last post to a working
condition.]
