I see that this is an optimization for making the patch series more
compact but I think that this addition logically belongs to patch #9
(which adds support for COMPILE_TEST) where the new code is required.

Moreover patch description for patch #2 lacks any comment about this
addition being a preparation for changes in patch #9 so I was quite
puzzled about its purpose when seeing it first.

Therefore please have mercy on the poor/stupid reviewer and don't do
such optimizations intentionally (or at least describe them properly
somewhere).. ;-)
