Thanks for the PR!

I wanted to let you know that I can't guarantee to review this any time soon (or the gcc version upgrading one either). One of the primary reason I use rules_mbed is so that I only need to take newer dependency versions when they are needed and can thus schedule the verification work for the numerous dependent mjbots projects accordingly.

I'm happy to keep these PRs open, and presumably you aren't blocked since you can just use your fork. When I do need to upgrade, I'll certainly work from them.

Thanks again!

Of course, make total sense. I am not blocked, just want to make those changes available in case they are valuables to others. No rush on my end to review them.
