Unable to build gogs due to gcc compiler warning #7682

I have attempted to build gogs from source as outlined here. However, I run into an issue when I attempt to build via the command go build -o gogs which gives me the following output:

# runtime/cgo
cc1: error: command-line option ‘-fno-caret-diagnostics’ is valid for vhdl but not for C [-Werror]
cc1: all warnings being treated as errors

For some context, I have GHDL (an open source simulator for the hardware description language VHDL) built using a GCC backend but that is the only thing that makes any sense as to why this error might occur at all when building any other projects. I don't know if this is a more generic GCC configuration problem that I've caused myself from the original GHDL build process, or something else entirely. Pointers to fix the issue would be much appreciated here.
gcc -v gives:

Using built-in specs.

I experienced a very similar error when installing gitleaks using pre-commit:

I also had ghdl installed:

GHDL 4.1.0 (tarball) [Dunoon edition]

I was on nixos, and was using a FHS environment to setup dependencies locally for a python project.

I avoided the issue by explicitly adding gcc to the environment (excuse my crappy nix):

{ pkgs ? import <nixpkgs> {} }:

(pkgs.buildFHSEnv {
  name = "project-env";
  targetPkgs = pkgs: (with pkgs; [
    gcc
    ...
  ]);
  multiPkgs = pkgs: (with pkgs; [
    gcc
    ...
  ]);
  runScript = "bash --init-file <(cat $HOME/.bashrc; cat .venv/bin/activate) -i";
}).env

I don't know if this would be similar for OP, but I'd suggest that the issue is that the gcc that is available in $PATH is likely to be improper somehow.
