C23 roughly says that {d,D}{32,64,128} floating point constant suffixes
are alternate spellings of {df,dd,dl} suffixes in annex H.
So, the following patch allows that alternate spelling.
Or is it intentional it isn't enabled and we need to do everything in
there first before trying to define __STDC_IEC_60559_DFP__?
Like add support for _Decimal32x and _Decimal64x types (including
the d32x and d64x suffixes) etc.
