Oops. I think I tested only with 'Inf'...
> Anyway, glibc seems to like NaN and infinity:
As I said: that Perl passes 'nan' without complaining isn't a guarantee
that the libc will. Before somebody suggests that Configure can test
libc/atof on nan/inf, I say that no, it can't, easily at least. These
corners of libc/libm/<math.h> are very nonstandardized: in other words,
a horrible mess.
