Comment (by cjones051073):

 I just stumbled over a comment in the home-brew recipe for gcc pointing to
 a patched gcc10 tarball for arm

 ttps://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/gcc.rb

 I've updated the gcc10 port to use this

 https://github.com/macports/macports-
 ports/commit/2e4c80e7ec18d1dd3b5d8222531598f653955e9a

 I don't have an arm machine to directly test on, but I checked the 'arm'
 version configured and started building fine on my macOS11(Intel) machine
 here. So I pushed it to the buildbots to see what it makes of it.

 If it works out OK, we could then make gcc10  the default on arm, instead
 of the current devel port. This port was always intended not for general
 use, but to test out upcoming versions. It was only used for arm in the
 absence of anything else...
