Hi,

This appears to be an ill-formed submission to WG21.

The paper does not contain (in its text) the WG21 paper number, and
it does not contain an e-mail address to contact the author, let
alone an author name (or a list thereof).

Furthermore, the C++ standard defers the *_HAS_SUBNORM macros
entirely to C; the only mention is in [cfloat.syn]:

"The header <cfloat> defines all macros the same as the C standard
library header <float.h>."

Given the apparent continued absence of interest in the details of
floating-point from C++, any changes here seem to be entirely in
the realm of WG14.
