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.
Just click on the button left/bottom of the compilation window. Cheers, Miguel
