i was wrong here about the correct treatment
the spec says that N is an unsigned decimal so negative
numbers must not be recognized at all
(so in this case the default rounds should be used and
'rounds=-4294965296' should be treated as salt)
but i guess the spec does not matter much in this case,
either we should be bug compatible with glibc or reject
such salts
