+ * real.h: Define REAL_VALUE_TYPE_SIZE as 96 or 160, as

+ based on REAL_VALUE_TYPE_SIZE. Use REAL_WIDTH to size
+ REAL_VALUE_TYPE. Define CONST_DOUBLE_FORMAT here. Use #error
+ instead of relying on later syntax error when REAL_WIDTH > 5.
+ * real.c: Define NE based only on whether or not we have a
+ full 128-bit extended type (not INTEL_EXTENDED_IEEE_FORMAT).
+ Require sizeof(REAL_VALUE_TYPE) == 2*NE. Unconditionally
