Hi,

not sure if I can help you here.
I once had the problem, that *my* library B depended on Boost 1.3x, and well, no way to change that.
So, I had to cope with 2 different versions of boost. Still, same compiler and ABI.

GCC might is able to let you interface between the ABIs, but maybe you'll need a library C that acts as a proxy to C++98 from '11(14,1y...).

To your concerns of boost being different for '98 and everything after: yes. I wouldn't let the versions mix.
So you'll need to contain the versions, in this case the lib b to a set of cpp files and private headers, not shared with A.
Any other case, you're basicly asking for trouble (but, might still work).

kind regards,

Jens
