I don't have gcc on brew.

My gcc is clang from Apple:

emacs on  master [$✘!?] 
➜ gcc --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr 
--with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.5 (clang-1205.0.22.11)
Target: x86_64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
