That looks ok but I wonder if we should also add '-Werror=vla' to it (
and remove it from common_warning_flags) to be in sync with what configure.ac

    # -Wvla is not applicable for C++

Hmm.  This comment is not actually fully correct.  With g++, you can write a
VLA and it will work, and also -Wvla will warn about it.  So we should
actually add that option to C++ as well.  (It is true that VLAs are not in
standard C++, and g++ with -pedantic will also warn about it.)

Oh right, just did a few tests and agree with your comment above. I agree that
it should also be added for C++ in autoconf then.

What about the attached?

That said, your patch LGTM given that the VLA remark was not appropriate.

Ok, both committed.
