gcc@13

brew install gcc@13 v13.4.0 GPL-3.0-or-later WITH GCC-exception-3.1

GNU C/C++/Fortran compiler collection, version 13 (parallel-installable with system GCC).

Why you might care

Install multiple GCC major versions side-by-side for compatibility testing or to use a specific toolchain without replacing your system compiler. GCC 13 includes newer language standards, optimizations, and diagnostics; useful for projects requiring explicit compiler version control or when Apple's Clang doesn't suffice.
