Great!

You can find it (on a Unix machine, not sure about Windows) by

  alr exec -- which gcc
  
If (again) you're on a Unix machine, it'll be under
~/.config/alire/cache/dependencies.

See https://gcc.gnu.org/gcc-12/changes.html (scroll down to the Ada section).

I _think_

  alr index --update-all
  alr toolchain --select

should do it
