I assume you meant "the code" here?

A while ago in Gnulib we moved all the variable declarations to where
they are used C99 style, since that is what we prefer for readability.

It isn't a blocker, but I think it would be a nice change for glibc as
well, at least for new code like this.

That is a minor thing I noticed and I figured was worth mentioning. The
patch itself looks good though. I'll let you decide if you want to
change that. Either way:
