17042 * real.h: Define REAL_VALUE_TYPE_SIZE as 96 or 160, as
17043 appropriate. Document need for extended precision even when
17044 MAX_LONG_DOUBLE_TYPE_SIZE is smaller. Define REAL_WIDTH here,
17045 based on REAL_VALUE_TYPE_SIZE. Use REAL_WIDTH to size
17046 REAL_VALUE_TYPE. Define CONST_DOUBLE_FORMAT here. Use #error
17047 instead of relying on later syntax error when REAL_WIDTH > 5.
17048 * real.c: Define NE based only on whether or not we have a
17049 full 128-bit extended type (not INTEL_EXTENDED_IEEE_FORMAT).
17050 Require sizeof(REAL_VALUE_TYPE) == 2*NE. Unconditionally
17051 define GET_REAL and PUT_REAL as simple memcpy operations; no
17052 need to byteswap or round.

17054 prompt error detection.
