> constant".

The standard has "integral constant expression". There are only a handful of
uses of "integral constant" and they're arguably mistakes that should be
changed.

> =D0=A1++ standard does not have "hexadecimal floating constant". =D0=A1++=
 standard has
> "hexadecimal floating literal".

The standard has "hexadecimal-floating-point-literal".

> =D0=A1++ standard does not have "floating constant". =D0=A1++ standard ha=
s "floating
> literal".

The standard has "floating-point-literal".

Both of those cases are grammar productions. GCC's diagnostics do not
necessarily refer to that formal term, because they're user-facing, and not
part of a BNF grammar.

Not all programmers are familiar with the terminology of the standard. If a
simpler or more colloquial term exists, it might be more user friendly to u=
se
that. In all cases above, the term used by GCC is shorter than the formal t=
erm
from the standard.

That said, I do think "floating constant" should be improved.=
