Btw. I've just check log of Win64 build #116 [1]
For instance in packet-vcdu.c:203 there is:
g_snprintf(juliantime, sizeof(juliantime), fmt, year, julianday, hour, minute, second, pb5_milliseconds);
and it compiles without warning, so if size value is known compile-time we don't need cast size to gulong.
(Uff...)
