because function requires explicitly __int64 because ID's are 64-bit, 
providing 32-bit int would ruin ID's that go over the 32-bit boundary. This 
may happen when I do text-to-int conversions using StrToInt and forget to 
put StrToInt64 instead.

In Borlangearcadero C++ Builder 2010 which I use, these functions output int 
and __int64 so compiler SHOULD be able to check these but unfortunately it 
doesn't - even if I enable W8102 Implicit conversion of '%s' to '%s' (C++) 
but it doesn't do what it is supposed to. I tried casting to wrong type but 
the warning is still not triggered.
