Approved with some minor trivial modifications.

                                       ^^^^^^^
Minor style nit: Two spaces after a period ("If NOSIDE")

I missed this one in the my first review, but there should be a space
after "(LONGEST)".

Just to be consistent, let's add a space before the "=" sign.

> +         "print sizeof (vla1\[i++\])"
