For Wine it doesn't really matter, since we can't use C++. For mingw-w64, 
however, it could be a big problem if it's not properly typed as a long. 
Overloads and template types would silently use 'int' where it should be using 
'long', and you wouldn't necessarily know until you see odd behavior in the 
app.
