Sorry to object here.  I would like to point out that defaulting to
dw2 on 32-bit if SEH is used for 64-bit is nothing good in general.
This is reasoned by the problems existing in dw2 in combination with
other compiler-generated binaries.


The patch does not change the default behavior for any target.  It only
makes configuring with --disable-sjlj-exceptions work in a situation
where it previously triggered a build error.

Precisely.
