This can be built with gcc-multilib 6.3 we already have within the repositories!

[gcc] PKGBUILDs for newer versions

null@example.com (throgh) — Tue, 31 Mar 2020 17:21:59 +0000

Hello you all,

within the last weeks I was busy creating further newer PKGBUILD-files for the newer gcc-multilib suite and named packages. So first of I'd like to thank Luke as I've used the files as examples. Attention therefore: You should use them incremental, so if you want version 9.3.0 on your system you'll need the previous version for building. Same with this one to repeat!
