The existing text tries to give semantics to the *_HAS_SUBNORM
preprocessor macros.
The "Proposal" removes any mention of these macros and just adds
general text about subnormals.
That seems a step backwards; the values of the *_HAS_SUBNORM
macros should continue to be related to subnormal behavior
of the implementation.
Put differently, are you suggesting to remove the *_HAS_SUBNORM
macros from the C standard? If not, they appear to exist
without any semantic definition given your proposal.
