3268 * c-typeck.c (build_array_ref): Added a check to see if array's
3269 index is greater than one. If true, then emit an error.
3270 (build_function_call_vec): Exclude error reporting and checking
3271 for builtin array-notation functions.
3272 (convert_arguments): Likewise.
3273 (c_finish_return): Added a check for array notations as a return
3274 expression. If true, then emit an error.
3275 (c_finish_loop): Added a check for array notations in a loop
3276 condition. If true then emit an error.
3277 (lvalue_p): Added a ARRAY_NOTATION_REF case.
3278 (build_binary_op): Added a check for array notation expr inside
3279 op1 and op0. If present, we call another function to find correct
3280 type.

3283 notation code is used in tree, if so, then transform them into
3284 appropriate C code.

3286 or RHS, if so, then build array notation expression instead of
3287 regular modify.

3289 colon(s) after square braces, if so then handle it like an array
3290 notation. Also, break up array notations in unary op if found.
3291 (c_parser_direct_declarator_inner): Added a check for array
3292 notation.
