[Bug: atof() can't parse "NaN"]
Thu Jan 6 22:55:00 GMT 2005
The newlib strtod and subsequently atof implementation currently does
not support NANs. I am working presently on an enhancement. It is
mostly working, however, I need to tweak vfscanf and a few unit tests
are not matching glibc behavior.
I should have something by end of day or tomorrow.
