(14:47:56) M`cc`: it seems prepared for 64bit filesizes
(14:48:28) M`cc`: I think the only thing that needs fixing is the parameter passing between pike and C
(14:48:59) M`cc`: afaik, pike passes numbers greater than 32bit as bignum 
14:49:52) M`cc`: so I think that around nb_send.c:360 it should check for bignum
(14:50:16) M`cc`: and check the value for the 64bit range
