Hmmm - I'm looking at the test matrix for RW_Mingw45 and 1 MinGW-32 as well as
track item #4375 - these are all failing.

It looks to me that there are only a couple of undefined symbols because the
autolink code is being enabled by BOOST_HAS_DECL which is now being used
to enable "visibility". This is likely even more confused as I believe
I've used this
or something like it to trick the compiler/linker into suppressing code
of code not otherwise explicitly referred to.

I see now that this has been in the works for some time and is not something
new. So it would seem that I can move my current trunk over to the release
branch and worry about this later.
