Subject: [PATCH] Silence warnings about using `long long` in C++03

We get these warnings because of the typedefs for 64-bit integers in
PhysFS's header files. The compiler will treat them as extensions and
will still compile it fine but it does mean we aren't strictly standards
conforming. Which really isn't a problem anyway. Probably.
