 Replying to [comment:11 kencu]:
 > gcc10-bootstrap will be able to build the current libgcc on all systems
 where the system can’t build it.
 > It is not yet finished, and there’s a PR up for it. That is the reason
 this has not been done already.
 > Once it is finished, the upgrade is not difficult; copy the steps I took
 to upgrade 10.6 to the current libgcc last year. One hour, max.

 I will look at the port history to find those, thank you!

 > gcc7 is not currently broken and I believe doesn’t need any fixing. It
 will be handled by the migration to libgcc12.

 I might have formulated it incorrectly. What I mean is that once I moved
 to `gcc11` and `libgcc` provided by `libgcc11` (on Leopard and SL), `gcc7`
 stopped working correctly, since its `libgcc7` is not there under `libgcc`
 port anymore. Fair enough, it may not be “broken”, but require re-building
 `libgcc7` or something else. But ''some'' extra step is needed,
 apparently.

 > Part of the reason gcc10-bootstrap is not finished is many questions
 about 10.6-on-PPC etc. If we can just focus on one-step-at-a-time,
 progress might be forthcoming. catap I think threw in the towel at a
 certain point. Let him get it working on the easier systems first, then
 everything upgrades, then we can see about offbeat stuff like rosetta on
 SnowLeopard and 10.6-on-PPC.

 I will discuss it with @catap, we are in touch. But in any case, Leopard
 is to be prioritized over any other PPC configurations, no questions about
 that.
