LGTM, but I don't have the privilege to approve any change so you'll
still need to wait for approval :)
Yea, but having a second pair of eyes chime in is definitely helpful.
And I think the behavior change should be announced in
https://gcc.gnu.org/gcc-12/changes.html, if it's approved.
Agreed.
The configure change is approved. And a change to the gcc-12
changes.html is pre-approved.
