+       * c-typeck.c (c_common_type): Choose the decimal floating point
+       type with the greater precision when determining a common type.
+       (convert_arguments): Warn if there is a mismatch between argument
+       and prototype for decimal float types.  Warn of conversions with
+       binary float types and of precision narrowing due to prototype.
+       * c-parser.c (reswords): Add _Decimal32, _Decimal64, _Decimal128.

+       Call builtin_define_decimal_float_constants for each type.
+       * c-lex.c (interpret_float): Decode decimal float types from CPP_N
+       flags.  Use real_from_string3, which can handle binary or decimal
+       floats.
