The cc-option filters out unknown flags which make the compiler error out. Note that Clang enables Wunused-command-line-argument by default and merely emits a warning but incurs no error, when it encounters such a flag. GCC on the other hand exits unsuccessfully when it is passed a flag of the form -Wunknown-warning, but no diagnostic is produced for -Wno-unknown-warning unless other diagnostics are produced.
