So why didn't you use the fix?

That is a very bad hack and I don't recommend using it. The only  
reason it works is that in 32-bit mode gcc int and long have the same  
size. It will break horribly if compiled as 64-bit. I don't know if  
you actually looked at the reason, but GLint is defined as long - so  
in is NOT int! That is why the compiler is (correctly) complaining.
