Kees - is there some online "gcc-4.4 checker" somewhere? This does
seem to work with my gcc. I actually tested some of those files you
pointed at now.

I use this one:

  https://godbolt.org/

Well, my *test* code works on that one and -Wvla -Werror.

It does not work with gcc-4.1.x, but works with gcc-4.4.x.

I can't seem to see the errors any way, I wonder if
__builtin_choose_expr() simply didn't exist back then.

Odd that you can't view warnings/errors with it.

But it's possible that it fails on more complex stuff in the kernel.

I've done a "allmodconfig" build with that patch, and the only issue
it found was that (real) type issue in tpm_tis_core.h.
