Beautiful, thank you!

Here it gets real interesting; it seems above you actually fix (or work
around?) a bug that allowed you to...

remove this monster. Although I am especially happy with it, I am
unsure exactly how it works.

and same here.
I tried your commit and it works for me. Rebasing `wip-bootstrap' onto
it was some work as you might imagine. The good news is that I finally
got it to "work" again (`wip-bootstrap' @ gitlab); the bad news is
that I have kept (or put back, actually) one of these 'setenv phases in
`gcc-mesboot0'. Well, that's for later worry; so this will need another
look when merging the scheme-only "wip-bootsrap".
For this patch: LVGTM (looks /very/ good to me!).
Thank you!
