Looks like something to do with the different exception handling under
MinGW & VC++.  See for example:

I have no idea how to resolve this, but I believe it is the case that
we are using SJLJ exceptions in our compiler and libraries.

You may be able to make it link by searching our libraries for the
appropriate symbols.  Whether the resulting program will actually work
is an entirely different matter however.
