[Cfp-interest 1579] Update footnote

[Fred J. Tydeman]

C2X, 6.6 Constant expressions, paragraph 5 has:

If a floating expression is evaluated in the translation environment,
the arithmetic range and precision shall be at least as great as if
the expression were being evaluated in the execution environment.122)

122) The use of evaluation formats as characterized by FLT_EVAL_METHOD
also applies to evaluation in the translation environment.

Two questions:
 1)  Should that footnote also mention DEC_EVAL_METHOD?

2)  Before the 122) reference, should we add something along the lines of:
If the two environments are the same, then the expression evaluations
shall be the same.
