Comment (by barracuda156):

 Replying to [comment:2 kencu]:

 Thank you for responding!

 > did you make any patches to gcc11/libgcc11 at all?

 No, not on 10.5.8. I would not mess with compilers unless it is absolutely
 necessary (not for “religious” reasons, I simply do not understand them
 well enough to improve).

 > I presume you have upgraded your default libgcc to libgcc11 as well.

 Yes, sure.

 > what linker have you set as default? ld64-97? or ld64-127? or something
 from Iain's repo, per the tools PR that catap had generated a while ago
 that has not as yet been merged

 `ld64-97`.

 I have not yet tried `xtools` on any of the systems yet (I have them built
 outside Macports, but did not use catap’s port so far).
