Thanks, I will try that, but first I am updating to get a clean state
after FORCE_CXX_STD has landed (not a complaint; I just don't want to be
in a partial state, and only debug in the new cleaner world).

I guess in theory whe might need a FORCE_AT_LEAST_CXX_STD which causes
max of what's specified to be effective, but that seems pretty
complicated.  The implicit point being that the number of packages
needing a foreign FORCE_CXX_STD should be pretty small, and overall the
combination of work and ick is better.

Yes, I pushed compiler to gcc10 and that didn't help.


I'll report again after another pass.
