autolink isn't an just a msvc concept anymore.  The boost autolink 
supports two functions:

a) creating and linking to a library with the correct abi
b) making the symbols to be exported from the library and imported into 
the application visible.  This is not supported under the name 
"visibility" for gcc and clang compilers.

Problem is that the C++ syntax decoration varies on various 
environments.  And this has lead - as you likely know - to problems in 
getting the visibility/export/import annotations correct for the 
serialization library - and likely others.  It's a mine field.
