[jonathan tan] This would be easier to understand if it was expressed
with bitshift, e.g. 1 << 31

This is actually ((1 << 31) - 1) because "unsigned long" is 32-bits
on Windows. But it's better to not use magic numbers and instead use
operations like this.

Nevermind. This breaks the build on 32-bit machines (even adding a few
"L" characters). I'll replace my magic decimal number with a magic
hexadecimal number.
