Typing "cc <TAB>" at the bash prompt does not give any hint.

The problem lies in the following piece of /usr/share/bash-completion/completions/cc:

complete -F _gcc gcc g++ g77 gcj gpc &&{
    cc  --version 2>/dev/null | grep -q GCC && complete -F _gcc cc  || :
    c++ --version 2>/dev/null | grep -q GCC && complete -F _gcc c++ || :
}

"cc/gcc/c++/g++ --version" do not print GCC, therefore the completion for cc/c++ is never installed.

I suggest to use this check instead:

  [[ "$(readlink -f /usr/bin/cc)" == "$(readlink -f /usr/bin/gcc)" ]]

However a problem still remains: when cc is not GCC, there is no completion. Therefore

  || :

should be replaced with

  || complete -F _minimal cc
