/**
* This file holds things that are platform-dependent such as
* dependencies on 64-bitness, help for when the platform does not
* have inttypes.h, and things like that.
*
* We need to convert pointers to integers and back for two
* reasons. First, hlife structures use the address of a node
* as its label, and we need to hash these labels. Secondly,
* we use bit tricks for garbage collection and need to set and
* clear low-order bits in a pointer. Normally the typedef
* below is all we need, but if your platform doesn't have
* uintptr_t you can change that here. We also need this type
* for anything that might hold the *count* of nodes, since
* this might be larger than an int. If inttypes does not
* exist, and you're compiling for a 64-bit platform, you may
* need to make some changes here.
