I'm not sure that it's that simple.

code in wserialization.dll makes calls in serialization.dll. So the
#includes for imported functions have to be be fore the "SOURCE"
statements. I originally did this a number of years ago and don't
remember whether or not it was painful. I recently mucked things up on
implementing the "visibility" features of gcc and clang. So now I'm
dependent on three subtlely different sets of rules. I know they are
all similar but slightly different so it means experimentation to get it
right. And of course I no longer have an MSVC compiler at my ready
disposal. And of course this isn't helped by the fact that when the
library fails to build on the boost test matrix - the error messages are
