That's right. The complete library structure is explained here:

http://inspirel.com/yami4/book/2.html

Ada is supported in terms of thick bindings and additional functional layer (the "general-purpose" part) on top of the core library, which itself was written in C++. That additional functional layer means that a substantial amount of functionality (this includes the tasking model, which the core part does not provide on its own) is in fact Ada.

The Boost license was intended for use in both open- and close-source projects. It is itself very liberal and similar in nature to BSD.
In short - once you have it, you can do anything with it, close it or publish it.

They are not functionally different, but the licenses are close enough that publishing both of them does not make any sense (that is, GPL version would not make sense if the Boost version was available).

The idea is similar to how AdaCore distributes GNAT - both GPL and Pro versions are essentially open-source, but are intended for distinct audiences.
