I think this is ok, but we should make sure to add a check in configure in the hotspot build-infra project.

Yes, we should do that. I was looking for something like this but couldn’t find any code so I went ahead and did it in the HotSpot Makefiles.

Do you want to add a check in configure with this bug or a separate one?

There is a bit more context in JIRA but the bottom line is that we shouldn’t be building the JDK with GCC 4.1.1. We have a workaround in just one place but that doesn’t mean the bug doesn’t show up in other places (especially new code). I’m suggesting to remove the workaround and blacklist this particular GCC version.
