If you use plain "int" and "unsigned int" (or gint and guint) they will be
64 bits on 64-bit platforms. But you shouldn't have to worry about this;
you shouldn't be using int/uint unless you know your value won't exceed
the range of a 32-bit integer. If you're going to exceed that value then
you probably have to use floating point or some kind of big-int library.

If you need a specific size integer, then use the gint32, gint64, etc.
macros from glib. But notice that gint64 isn't defined on all platforms,
there is a preprocessor symbol defined in glibconfig.h that tells you if
it is.
