This badly requires a target maintainer.

Doesn't reproduce on Cygwin, and I don't have a current mingw cross compiler
handy.  It would be best if Kai can look at this as I'm up to my neck in ada at
the moment, if he hasn't found time in the next four or five days I'll try and
investigate.

Well, this seems to be caused by member exceptionDestructor in __cxa_exception
structure.  As a destructor has also __thiscall convention, we need to specify
it here for 32-bit Windows target.

I am just about to test a patch for it.
