all that's needed is to cast ints to long on alpha ... I have written some
macros to do that ... they might be usefull for these cases ... maybe put
in glib.h ???? ... or gnome.h ???

/*a few macros to reduce compiler warnings*/
#if (SIZEOF_INT == SIZEOF_VOID_P)
#	define PTOI(p) (gint)((gpointer)p)
#	define ITOP(i) (gpointer)((gint)i)
#elif (SIZEOF_LONG == SIZEOF_VOID_P)
#	define PTOI(p) (glong)((gpointer)p)
#	define ITOP(i) (gpointer)((glong)i)
/*I doubt there is a such a platform, but why not*/
#elif (SIZEOF_SHORT == SIZEOF_VOID_P)
#	define PTOI(p) (gshort)((gpointer)p)
#	define ITOP(i) (gpointer)((gshort)i)
#endif

then use these macros as casts
