I have no access to a 64bit cygwin, but if the patch works there, shouldn't it
be possible to make it available to 4.9.0, instead of 4.9.1? After all, the
bootstrap (with --disable-sjlj-exceptions) fails and this cannot be worse with
the patch. Also there is no impact on other (non-cygwin) configurations.
