variants.h : integer constant out of range

[Hongbo Yang <hyang@xxxxxxxxxxxxxx>]

In variants.h, there is a macro definition:

#define V_PF_FLAGS              0xffffffff00000000 /* Prefetch flags */

While compiling the programs that use this macro using GCC 2.95.3 it
always complains that "integer constant out of range".
