Proposed resolution:
This wording is relative to N5032.
Modify [cfloat.syn] as indicated:
-1- The header <cfloat> defines all macros shown above the same as the C standard library header <float.h>.
[ 2026-01-16; Jonathan provides improved wording ]
[ 2026-01-16; Reflector poll. ]
Set priority to 3 after reflector poll.
"Could be just 'The header <cfloat> defines all macros shown above the same as the C standard library header <float.h>."
"That would resolve my concern to require C++ implementations to actively `#undef` things from <float.h>.
It should be up to the implementation."
This wording is relative to N5014.
Modify [cfloat.syn] as indicated:
-1- The header <cfloat> defines all macros the same as the C standard library header <float.h>, except that it does not define any macros specifying characteristics of C decimal floating types or C interchange floating types.
Consider [climits.syn] paragraph 1:
The header <climits> defines all macros the same as the C standard library header <limits.h>, except that it does not define the macro `BITINT_MAXWIDTH`.
Similarly, <cfloat> is missing various macros from C's <float.h>, but this is not stated.
