Nasty, eh?

I guess not. Also, even if we get the compilers fixed, it will be some
time before we can deploy the kind of change you're proposing (which I
do agree looks a lot nicer: #ifdefs are ugly if for no other reason
that they lie outside the brace levels).

It will probably take about 5 years after a new version of GCC which
has this fix before we can trust it to produce correct code for the
kernel.
