this one can be easily fixed

(it seems gratuitous complexity in the standard, but that's how it is)

i don't know the internals of floatscan though
i guess the 'pok' argument tells if putback is ok
and if it's false then at most one putback is allowed

if arbitrary long putback is possible when pok==1
then i can create a patch (that always returns the
same nan for all correct nan(...) formats)

otherwise we can add support for "nan" and "nan()" only
