I've added the fix into master. I was somewhat weary of adding this into the stable branches as although the fix seems self-contained, it has the potential of affecting all postgis usages. Given it does not affect most common usages of postgis (it would have been reported ages ago in that case), 7.0 seems like a reasonable milestone, you can easily backport if needed.
