decl2.c (lang_decode_option): Set default line-wrap length to 72.

Browse Source 
2000-01-19  Gabriel Dos Reis  <gdr@codesourcery>

        * decl2.c (lang_decode_option): Set default line-wrap length to 72.

        * typeck.c (composite_pointer_type, common_type,
        comp_target_parms, c_sizeof, expr_sizeof, build_array_ref,
        build_function_call_real, convert_arguments,

        build_c_cast, build_modify_expr, get_delta_difference,
        build_ptrmemfunc, check_return_expr): Replace 'ANSI C++' with
        'ISO C++'.  Fusion consecutive calls to diagnotic message routines
        into a single one.
        * typeck2.c (readonly_error, abstract_virtuals_error,
        process_init_constructor, check_for_new_type): Likewise.
