I am afraid, but this did not work in gcc 4.3.0, now. I add this, but still
failed with a SIGFAULT...
I attach my litter test case file, please try to compile it with g++ 4.3.0, and
it will fail...

The testcase fail g++ 4.3.0

>From this bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11893, we know the
typeof operator make all things correctly. But in gcc 4.3.0, this operator
failed, too.

It is a regression now. It worked in 3.4 and doesn't work in 4.x. That's why
I'm still using GCC 3.4.6.

Fixed for 4.4.3.  The patch for 4.4 applied fine to 4.3, but didn't fix the bug
there for some reason.

I do get a warning now, saying this attribute only applies to function pointers.
