10 secondes de recherche sur google et j'ai trouvé ça :
"no I replaced the call to _strtoui64 by both alternatives. In both cases it doesn't complain about this line anymore. Then I got many new errors from different files but I now figured out that in this instance of all my tests I forgot to link the ws2_32.lib. -> it compiles with both strtoull and strtoul, thanks!"

Donc de ce que je comprends il avait oublier de linker "ws2_32.lib" et on peut remplacé _strtoui64 par "strtoull" and "strtoul".
