I apologize for not having any opinion on the patches themselves, but
let me point out that it's better to base these patches on HEAD
(master branch) than REL_12_0, because all new code is committed to
the master branch, whereas stable branches such as REL_12_0 only
receive bug fixes.  Do you have any specific reason to be working on
REL_12_0?
