The approach has the big advantage that you can step through the code in a
debugger, and that the entire block expands into a single statement.
(The original approach from gdb-7.2/gdb/exceptions.h has no unbalanced
braces, but the expansion is 2 statements, not 1 statement.)

Actually the unbalanced braces have the advantage that you immediately get a
syntax error if you forget the DONE_MSVC_INVAL token at the end. It happened
to me already.
