The GNU Project's attitude toward standards is that they represent
what other systems are likely to do, and what users are likely to
want.  So we don't ignore them.  But neither do we "obay" them or
"comply" with them.

Regarding __typeof__ and Sun C 5.8, I see three choices:

1. Generally avoid using __typeof__.

2. Not support compilation with that compiler.
That approach is painless _for us_ if GCC does the job
on those systems.

3. Use __typeof__ and add a kludge as a workaround when using that
compiler.

As a general matter, my preference is 3 (if it is not much extra
work), next 2, and least of all 1.  But I don't know the details of
the situation, so I'd rather that the decision be made by people who
do.
