'depercated' in a warning is issued for a gcc extension which will be
    removed in some future rlease. For example, with gcc 3.4.0, this
    code:

    int main()
      {
        foo:
      }

    results in this error message:

    label_at_compound_statement_end.c: In function 'main':
    label_at_compound_statement_end.c:5: error: label at end of compound
      statement

If you place a semi-colon after the label warning (error with 3.4)
    vanishes. ISO C requires a semi-colon after the label.
