Also, the description above merely says we use gcc-9 instead of gcc-8,
without saying if that is a good change or not, which is another thing
that needs to be said.  In the larger context, if we aim to try different
compilers, we should know which other ones we are using, and if linux-gcc
job is meant to test gcc-8 (because we know there is another job
that tests gcc-9), the change was a bug.  But because you said it
was not a bug, it made it unclear if that is merely an observation
or it was pointing out our earlier mistake that should be corrected.
