[Cfp-interest] Classification macros and clearing flags

[Rajan Bhakta]

I think we don't need to say anything here just like for a number of other 
functions. Like what the IEEE-754 list said, I think we should leave it as 
is.

Currently, TS 18661-1 has these words:

[5] The C classification macros fpclassify, iscanonical, isfinite, isinf, 
isnan,
isnormal, issignaling, issubnormal, and iszero provide the IEC 60559 
operations indicated
in the table above provided their arguments are in the format of their 
semantic type. Then these
macros raise no floating-point exceptions, even if an argument is a 
signaling NaN.


Do we need to add words that those macros do not clear any FP exceptions?
