Read the archives.  It's only a problem if you try to throw an exception
inside a callback that is called from a foreign library AND that library
has not been compiled with -fexceptions.  General win32 API calls work
fine, callback functions that don't throw exceptions work fine.  If you
never compile code that involves those circumstances, then you can use
DW2.  For the Cygwin gcc packages though I think such an assumption
cannot be made, so the slower but safe sjlj is used.  You would have to
ask Gerrit and/or cgf for the reasoning.
