But why not make a boost trunk clone on gitorious.org and start a boost stable branch yourself? It would probably need some
..
3. Boost is configured mostly with defines. So upgrade of compiler version for gcc-4.3 to gcc-4.4 may break ABI just because some new feature comes and something is changed in class layout.
Ok, I better understand your approach now. But I also have to say that this shows yet again how a boost::stable design may be fundamentally different from what boost does: one great use is to abstract away many compiler differences. If boost was to be binary stable and still serve this purpose, this would mean that for one buggy compiler boost supports, all compilers would have to pay the price because the ABI must be designed in a way to be able to incorporate the particular workaround.
