Here is the text version.  If this is OK, I will make an HTML version for WG14.

The binary getpayload functions (WG14 N2478 Annex B.11 and F.10.13.1):

 double getpayload(const double *x);
 float getpayloadf(const float *x);
 long double getpayloadl(const long double *x);

have 'const' in the parameter.

While the corresponding decimal functions:

 _Decimal32 getpayloadd32(_Decimal32 *x);
 _Decimal64 getpayloadd64(_Decimal64 *x);
 _Decimal128 getpayloadd128(_Decimal128 *x);

are missing that 'const'.  This was an oversite by the CFP committee.

'const' should be added to the three decimal getpayloaddN functions as:

 _Decimal32 getpayloadd32(const _Decimal32 *x);
 _Decimal64 getpayloadd64(const _Decimal64 *x);
 _Decimal128 getpayloadd128(const _Decimal128 *x);
