You get that warning only for the x64 build? You should also get it for
the win32 build. Because you can't shift 32 bits for a variable that's
also 32-bit (doesn't make any sense), and especially not for a *signed*
32-bit variable.

sizeof(int) is 4 for both 32 and 64 bit builds. At least with Windows
compilers. If you want to use 64-bit types, you have to use __int64 instead.

Note: while sizeof(int) is 4, sizeof(size_t) is 4 on win32 but 8 on x64.
