I believe that this is needed for dw2 exception support.  This doesn't
work with gcc 3.0.4, so I don't think you need to worry much about old
binaries.

I noticed this when I was fixing the gcc dw2 exception support.  Changing
it didn't seem to have any affect on the v3 or g++ testsuite results, but
it seems the correct thing to do.
