I've tried patch 1 and 2, but they do not work. The fact is that the code is not used in the backend, because strtod("NaN", endptr) works. (isnan(strtod("NaN", endptr)) is true).

I should also note that isnan((double)nan("")) is true (works).

I will also report to NetBSD that isnan((double)NAN) does not work on mips.
