--- Comment #3 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
On macOS Big Sur Intel, Homebrew builds gcc-10 from the 10.2 release sources
(https://ftp.gnu.org/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.xz) with one extra patch
at
https://raw.githubusercontent.com/Homebrew/formula-patches/7baf6e2f/gcc/bigsur.diff
(which is basically Iain's commit at
https://github.com/iains/gcc-darwin-arm64/commit/556ab512)
The compiler is build with:
```
../configure --build=x86_64-apple-darwin20
--prefix=/usr/local/Cellar/gcc/10.2.0_2
--libdir=/usr/local/Cellar/gcc/10.2.0_2/lib/gcc/10 --disable-nls
--enable-checking=release --enable-languages=c,c++,objc,obj-c++,fortran
--program-suffix=-10 --with-gmp=/usr/local/opt/gmp
--with-mpfr=/usr/local/opt/mpfr --with-mpc=/usr/local/opt/libmpc
--with-isl=/usr/local/opt/isl --with-system-zlib --with-pkgversion='Homebrew
GCC 10.2.0_2' --with-bugurl=https://github.com/Homebrew/homebrew-core/issues
--disable-multilib --with-native-system-header-dir=/usr/include
--with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
SED=/usr/bin/sed
```
We've always done it that way, the only recent change to that is pretty much
that we use the unversioned symlink
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk instead of the versioned
directory (/Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk) because
since Big Sur, Apple is labelling their SDK with minor version numbers and that
breaks for people who don't have the same exact version of the command-line
developer tools.
