Boost.Move, Boost.Interprocess, Boost.Container, Boost.Intrusive

I think my libraries have high C++03 compatibility features. I run the 
regression tester for MSVC.7.1 and GCC 3.4 and all my libraries work 
correctly in that environment. At work we use C++03, we have a ton of 
C++03 software and that's not going to change in many years, that's 
typical in many industries that need to maintain software for decades.

I don't think so, if I have time, I will continue developing my 
libraries (like Boost.Container) with newer features (like new, 
no-standard containers). Portability is also nice feature for a library 
(consistent performance-behavior across different compilers/platforms). 
E.g. Boost.Move should explore destructive move semantics not available 
in the language.

Yes.

No idea. I know Boost.Move is quite used for quite in many projects that 
need to support both C++03 and C++11, but that's the main goal of the 
library ;-).

Best,
