The fact that Git may utilize HTTPS protocol doesn't imply that you can
list its contents with a web browser.


If you have issues cloning GCC's official GCC repo, here is some mitigation:

  # Create an empty repo with a working tree.
  mkdir gcc
  cd gcc
  git init

  # Add mirrors by hand.
  git remote add origin https://gcc.gnu.org/git/gcc.git
  git remote add github https://github.com/gcc-mirror/gcc.git
  git remote add tuna https://mirrors.tuna.tsinghua.edu.cn/git/gcc.git

  # Fetch from reachable mirrors first.
  # TUNA is unlikely to be unreachable from you, however it is
  # slightly left behind other mirrors.
  # This will fetch the bulk of the repo.
  git fetch tuna

  # Fetch more data from another mirror.
  # Objects that have been fetched from TUNA will not be fetched again.
  # There's supposed to be much fewer bytes to download.
  # GitHub is slower, but is less likely to be blocked by Chinese ISPs.
  git fetch github

  # Check out the master branch and initializes the working tree.
  # This is usually a bit behind `origin/master`.
  git checkout -b master github/master


  # Fetch data that have not been mirrored yet.
  # You may postpone this until you have access.
  git fetch origin

  # Set up its tracking branch.
  # You only need to set it once.
  # Note: This requires a successful fetch from `origin`.
  #       If that is not possible for you, please skip this step.
  git branch master --set-upstream-to=origin/master
