No, the explanation can be found in another mail from Sander Vesik.

You're relying on semantics of a special version on a special plattform.
This might even vary between different versions, OSes or CPUs and as
such should be used with extreme care because it might bloat the code
on a different plattform just to prevent a warning on another.

I don't specially care about the readability of a single block in a
header file because problem debugging and reproducing is much easier
in preparsed code anyway where only to correct and readable statements
will/should show up.

I'm probably not the right person to comment this question as I don't
know much about either setjmp/longjmp or DCE. Maybe you can explain what
this would mean and where the benefits are?
