Eww :)

That would work.

I would suggest:
#if SIZEOF_VOIDP == 8
#define FLAC__64BIT_ARCH 1
#else
#define FLAC__64BIT_ARCH 0
#endif
Setting a #define to either `0` or `1` means that it can be used in code like
if (FLAC__64BIT_ARCH) {
// 64 bit code
} else {
// 32 bit code
}
and the compiler will syntax/type check both branches but optimises one
away completely.
