For your consideration, here's a preview of some new seh_try_macros-type stuff...

Of course the main limitation is that this requires gcc, which means
the macros can't be used in Wine itself. They might be useful for
Winelib apps though.

You cannot re-raise exceptions after finally, the finally block has to
run at unwind time, not from the exception filter. You should probably
use the existing __FINALLY macro for that.

IMO you shouldn't use a variable at all, you should do everything on
the stack. Otherwise it won't work when an exception happens in the
middle of the exception code.
