Here I meant to add that of course we have discussed deprecating
-mno-cygwin and offering a real MinGW cross in its place, which would
have its own back-end, and thus could have a different exception
handling model.  But by the time you've done all that, you might as well
just package a separate gcc named "gcc-dw2" or whatever and have them
both installable in parallel, to please everybody.  This is what Danny
did with his 4.2 MinGW releases.
