/* The floating-point expression evaluation method.  The precise
   definitions of these values are generalised to include support for
   the interchange and extended types defined in ISO/IEC TS 18661-3.
   Prior to this (for C99/C11) the definitions were:

-1  indeterminate
	 0  evaluate all operations and constants just to the range and
	    precision of the type
	 1  evaluate operations and constants of type float and double
	    to the range and precision of the double type, evaluate
	    long double operations and constants to the range and
	    precision of the long double type
	 2  evaluate all operations and constants to the range and
	    precision of the long double type

The TS 18661-3 definitions are:

-1  indeterminate
	 0  evaluate all operations and constants, whose semantic type has
	    at most the range and precision of float, to the range and
	    precision of float; evaluate all other operations and constants
	    to the range and precision of the semantic type.
	 1  evaluate all operations and constants, whose semantic type has
	    at most the range and precision of double, to the range and
	    precision of double; evaluate all other operations and constants
	    to the range and precision of the semantic type.
	 2  evaluate all operations and constants, whose semantic type has
	    at most the range and precision of long double, to the range and
	    precision of long double; evaluate all other operations and
	    constants to the range and precision of the semantic type.
	 N  where _FloatN  is a supported interchange floating type
	    evaluate all operations and constants, whose semantic type has
	    at most the range and precision of the _FloatN type, to the
	    range and precision of the _FloatN type; evaluate all other
	    operations and constants to the range and precision of the
	    semantic type.
	 N + 1, where _FloatNx is a supported extended floating type
	    evaluate operations and constants, whose semantic type has at
	    most the range and precision of the _FloatNx type, to the range
	    and precision of the _FloatNx type; evaluate all other
	    operations and constants to the range and precision of the
	    semantic type.

The compiler predefines two macros:

__FLT_EVAL_METHOD__
      Which, depending on the value given for
      -fpermitted-flt-eval-methods, may be limited to only those values
      for FLT_EVAL_METHOD defined in C99/C11.

__FLT_EVAL_METHOD_TS_18661_3__
      Which always permits the values for FLT_EVAL_METHOD defined in
      ISO/IEC TS 18661-3.

Here we want to use __FLT_EVAL_METHOD__, unless
     __STDC_WANT_IEC_60559_TYPES_EXT__ is defined, in which case the user
     is specifically asking for the ISO/IEC TS 18661-3 types, so we use
     __FLT_EVAL_METHOD_TS_18661_3__.

   the value provided by the compiler assumes the widest setting.  */
