changing jobmask [32bit to 64bit]

[Lord Ganja]

Anybody willing to help me about this? I successfully added custom jobs using Neo's Guide, but I still want to get rid of the warnings when compiling.

srcmapitemdb.c(361): warning C4293: '<<' : shift count negative or too big, undefined behavior

and as Neo, said

Here we check the job masks that is specified in item_db.conf. There is one limitation, however.
Currently there is only 1 more slot left in the job mask since it is 32 bit. In case you need to add more you will need to
change the variable to 64 bit.

So can anyone help me change 32bit into 64bit variable?

Thanks in advance!
