Gaby, I am having a problem with this approval for two reasons:
1) We must not change the ABI on an active release branch, especially not
as late on a release branch, which is supposed to be in deep maintenance
mode.
2) Approving such a change for 3.3 without checking the situation on 3.4
means that we may have ABI breakage from 3.3 to 3.4, and yet again (just
in the other direction) from 3.4 to 3.5.
I raised this once, and I repeat it: IMnsHO you must not approve this kind
of changes without first checking the situation on 3.4.
